WEIRD Japanese STATIONERY you've never seen before

[@argentum9195]

I grew up watching my classmates bringing these fancy and expensive pencil boxes...it's soo nostalgic...although I never got the opportunity to own one, but realising how far I made without having those is such a good feeling..although the eight year old me would have done anything to get one of those things...even now I love cool stationeries like those aesthetic and vintage stickers or washi tapes but my parents think they are a waste of 💰 soo I diy them 🤗

[@lovesre]

aww i wish i could’ve gave 8 year old you one of these 😭💗💗

[@akira8335]

as a girl who owned one believe me they suck, some little rust somewhere and you done with it, once it slips and falls down you done with it, phew and if the magnet gets spoiled you done you cant even use it like a normal one and then my parents didn't even buy me a new one it suked the shiet out of me. But then again i understand you coz they looked pretty and expensive but that's it . those little shiets

[@nursejanainholland1978]

I was one of the fairly poor kids in my class but my mom worked as a cashier at a department store and got a great employee discount. She brought me home a Hello Kitty box similar to these and I loved it! My classmates were jealous. I wonder now what happened to it? I got it in 1977 or 1978.

[@happycure]

Aww.samee

[@zara5325]

Me too, my classmates had fancy pencilcases that were worth my father’s salary for a week and I used to make pencilcases for me out of shoeboxes. I think poverty brings creativity 😂

[@michailp3021]

In the 80s in Greece, we had a plethora of Japanese imported toys and stationery. Essentially, many of us grew up surrounded by Japanese products, often without realizing the extent of our exposure to them.

[@Decadenttia]

We experienced the same in Spain. These kind of pencils cases were easy to find in particular and almost every kid had one or had sibblins who had one.

[@Kalani_Saiko]

Same in Australia, but in the 00's and 2010's

[@chronicfish]

ναι ρε φιλεεε!!!

[@somethingdifferent...]

same here in France/Switzerland !

[@dieseldragon6756]

From my recollections of a mid 80's UK childhood, we were getting these imported to us as well. 😇

[@Brienna82]

I had some pencil cases like these when young, although not with these exact designs of course. I loved playing with it and just opening all the different compartments. A sort of fidget toy before that concept even existed for sure.

[@chilliwaterlickingecko5113]

Same here .. like batman spider man, James bond , transformers etc So many variations

[@eepyknight]

Yes exactlyyy my adhd kicked in hard with these

[@vickyhallsworth928]

I love them. We still have similar in the U.K. I grew up with pencil cases like these. I know showing my age. 😂❤❤❤❤❤

They still exist if you know where to look xD

[@sarahkellett4926]

Same for me. These bring back so many memories.

[@notyouraveragewitchx]

i loved these pencil cases growing up in the 2010s! the good quality ones with multiple features (like the first red hk case in the video) were a bit pricey but the basic ones were just as cute! such fun times fr

[@LyraPyxisVT]

Didn't even know these existed and I was 8 in 2010

[@worstusernameintheworld9871]

[@partlypaula]

As someone who grew up loving stationary (and still do!) I absolutely love this video! Its so interesting to see the different cases and different compartments. Thank you for showing us these cases because I'm not sure if i would ever see cases like these had you not shown it. :)

[@JagoffCitizen]

"stationary" means the next but one word you used😆

[@Drawwithauto]

​@@JagoffCitizen You're right, most people do not know that. "Stationery" (is a noun) means school supplies, and "stationary" (is an adjective) means anything that is still.

[@Decadenttia]

How crazy is that I remember having these kind if pencil boxes as a child in the 80's and they were rather easy to find in Spain's stationary shops. Literally most of my classmates had one.

[@MoonshineSunset]

In México too, they were everywhere for a good while, and mine wasn't expensive, they were cheap, but now that I think about it, they could have been chinese copies or something 😂

[@thehometrainer]

we had the spanish version "Cuca Dols "that was amazing

[@Lea-bw9wj]

I'm Aussie and I had a couple of similar pencil cases to the 3rd one in the mid 80's. They were somewhat popular at the time.

[@AstorReinhardt]

I actually have a few of these, also vintage. We have a lot of people who are of Asian descent living here in WA state (specifically around Seattle) so a lot of things from overseas countries can end up in our thrift stores. That's how I got mine. They're so cute and I wish we had them in America...useful and adorable lol. Mine are pretty basic when compared to the Hello Kitty or the Magical House ones you have. I think my favorite is between those two...they're both awesome.

[@AlphineWolf]

My aunt gave me one for my birthday 😅. Its still in mint condition. It's a simpler one

[@Kalani_Saiko]

Washington?

[@Aimz360]

I love that house one, i've never seen anything like it before! Personally, as an artist with no space for a decent table, I like the black one, it would be perfect for my tiny art table and it's multi-functional. I had a similar pencil case as the first one with the dail. I got it at Disneyland Paris back in the 90's and there were buttons for each compartment and a magnetic lid. I spent more time launching a large compartment for protractors/extra pencils than I did actually using it as a pencil case.

[@carpediem5343]

I always loved these pencil cases that have compartments and pop-out mechanisms. Very nostalgic..brings back memories growing up

[@dimitriskafeneioPlataria]

I remember girls in my class having similar pencil cases back in elementary school, probably from Taiwan or Japan, since the most stuff back then were made in those countries. This September, when i was out to buy some stationery for my 7 years old niece, i saw some similar pencil cases after all these years, in a big store which sells mostly stuff from China, and i felt nostalgia.

[@bethenecampbell6463]

I was in school in the 70s and 80s. In the US these kinds of pencil cases were not common. We were encouraged to bring a cigar box from home that we could decorate. Cigar boxes were so uncommon that stores that sold school supplies had them, and they were made for pencils and erasers, never had cigars in them! I think the tray in the first box you showed was meant only as a flat surface to write on, not storage. My favorite was the dollhouse one.😊

[@johanna006]

The tray is for rulers.

[@juliecolemannelson6849]

They were pretty common in Hawai'i

[@jenniferpearce1052]

They were very common where I lived in southern California.

[@bunbun25055]

😲 I love these so much!!! I had a boring pencil box growing up. They had no compartments and you just tossed everything inside of it and went about business. The Magical House one is so unique and cute! Reminds me of Polly Pocket. I would have loved having it as a kid! Heck... I would love having it now! 😂

[@tainadelcaribe]

As someone who grew up in the 80s/90s and since childhood has loved stationery, still does, and I’m still collecting, I missed these! I had some as a child in Puerto Rico and there were also so many reproductions made with different front covers. I traveled to SKorea for a few months, visited Japan and got some cute stationery. This is all to say that on my way back I had a layover in Shanghai and I bought some of those at the airport to s]give to my friend’s kids. I wished I kept one for myself. 😅 Also, I had a couple and one was very similar to that first red Hello Kitty one s]you showed; it just didn’t have the dial, it was all buttons and pulls and I think (it’s been a minute😅) it look like a bus.

[@fine.polish]

I got so much nostalgia from watching this! In the 90s, I had 3 pencil cases with similar features, and 2 of them had the buttons to open up different compartments, but the feature I loved the most was the ability to set the date with wheels on one of them. I ended up giving them to my niece, but very reluctantly!

[@rachel_vill]

I actually had pencil cases similar to those. The more pop ups or doors you had on your case, the more you felt superior. That was then

[@karines1856]

OMG! As an 80's kid, I had one of those pencil cases!!! You brought so many nice and cozy memories from watching this video. Thanks! 💓

[@sethusk]

My favorite is the Hello Kitty one, what a marvel of engineering! I would love to have something like that when I was a kid.

[@AE1OU]

I remember as a kid back in the 90s i had something similar to that red hello kitty design but mine was green instead and had kerokeroppi as the mascot. The one i had wasnt as advance with that dial thing to open different compartments but mine had many different compartments that flips out such as a compartment for pencil sharpener, scissors, ruler slots, memo pad, cellotape and even a flip out magnifying glass.

[@SumireKarol]

I had a pencil case very similar to that Hello Kitty one when I was a kid back in the 90’s, but I’m from Spain! This feels so nostalgic 🥺

[@Cynshine100]

I remember that Hello Kitty one! I didn’t have one because my mom isn’t down with impractical items. But I had friends with them and I played with it too! It’s so cute! ❤❤❤

[@sarahbowman7566]

There were many versions of these pencils cases here in the UK in the 1980's and here they contained all of the stationery items, not just paper place holders.

[@rhyfelwrDuw]

As a Hello Kitty fan, I love the HK, but then again I'm a stationery fan so I love them all! The house was awesome! Perhaps the little section in the house roof could be used to put your pencils in when you're doing your homework etc?

[@annakwong964]

Thank you for doing this video. It does bring back memories over 20 years ago when I had one of these (not exact one). It meant a lot to me when my family got for me. Till this day I am so into these cute and useful supplies in life. My fav is the Hello Kitty and Sweet Home.

[@belendemaria1989]

I had one like this when I was a kid in the 90s in Argentina. It was sort of like the second one. I'm pretty sure the slim trays are for your geometry set. That was really useful, as mine kept getting buried in the bottom of my backpack and broken.

[@khalfayoussef]

Indeed Japanese stationery is the best. Keep up the good work as always, Minori.

The first one was SO COOL but kinda violent 😂 I’d flinch every time I needed to open something on it

[@cymorilgray1891]

Soooo cute! I am showing my age I know (45) but I live in U.K. and I remember having a hello kitty one similar to this! these type of pencil cases were very on trend at the time and all the girls had them!😍 Also we collected and swapped “rubbers” or erasers as you call them. But they were novelty ones and you NEVER used them lol! So many times you would need a rubber in class and have a pocket full of your fav ones and nothing to actually “rub out” with 😂😂😂

[@sisabell]

I had a Hello Kitty one back in the early 2000s in the US! I might still have it around somewhere... it was sort of similar to the Hello Kitty one here, but instead of the dial it had several buttons you could press to make the different areas pop out/up!

[@angrybearhaechanie]

i'm an indian and i literally grew up using these type of stationary boxes..i remember we used to discuss who's box was the best in the whole class lol

[@fruitbattery]

I'm Norwegian, and I had one of these as a kid in the early 90s (I believe it was Little Twin Stars themed, because I had several sets of LTS themed things, toiletries, lunchbox and flask etc), and the shop I work at sold a couple of different types of these "pop-up pencill cases" as late as last year and it really brought me back to the 90s

[@Princess_Ally]

Even though japan has some weird and random stuff like these pencil cases but they are so cool! (Sorry i didn't comment in the last video 😅) and i also love that minori didn't throw stuff away that she loved instead she treasures them how nice of her 😊 ❤

[@Sorchia56]

I LOVE these cases! So fun. I recall dropping my pencil case like a bad habit once Star Wars came out! My big brother and I got the Deluxe Star Wars pencil case, metal lunch pal, bags, bedding, toys…I still have mine! I’m 55. They are on a shelf in my library. I will always be a Star Wars junkie. 😂

Firstly, your voice has a great rhythm, effects a great soothing magic on listening ears .Moreover, its nice to see childhood memory once again it's pretty cool. Thanks

I had some of these in the 90s cuz they still made them. I loved the multiple cartridges that you could pop out and use. It was like a secret puzzle box. The nostalgia

[@jellyem]

Aw I remember owning a case kinda like some of those when I was younger~ I love that Hello Kitty one, all those hidden compartments are so cute!

[@ldnroses]

I was born in the 90s and went to kindergarten in east Asia. I had pencil cases like this and loved them!! Everyone in my class had one too, all mostly either hello kitty, my melody or other Sanrio characters ❤

[@alnicacherelledelapena5231]

I LOVED those pencil cases. I would also have those cute little food erasers that separate into pieces and i would pretend to be a bakery with the pencil case 😭. Stationaries nowadays are more minimalist and although theyre still cute, i do miss my very extra, almost unusable stationaries lol

[@atiqafarooq6897]

i love the pencil cases they are so unique and some of them actually more convenient to use.

i have these type of pencilcase that is sanrio themed and it has a rubber and removable sharpener and at the back of the pencil case there is a white board

[@nuhanadhirah]

I love all of them but I'm obsessed with the magical house pencil case

[@andybrown4284]

I had one similar to the grey but used it more as a desk tidy than a pencil case, regular one for taking to school was just a basic 2 piece metal case that opened on a hinge although it was starwars themed. From the paper in drawer in the first it looked like that part was meant for flat things like a protractor, longer ruler and set square

[@lunabunny_0521]

I love the hello kitty one, but the last one was my favorite. I would've definitely played with that as a kid. ❤

[@user-vx7do5sr5q]

[@crysty1713]

I am the biggest fan of stationary and proudly showoff them and I used to buy lot of these boxes as well like I think I was the only student who used to change pencil boxes and stationary frequently like very very frequently , I still do so. this video gave me nostalgia like I really hope I kept these pencil cases.

[@nadyamelaniputri2716]

Uuw i love this type of pensilcase. I have those things a lot when I was a little. Like literally collect everything, when they update the new one, I'll always bought it. Even I have the 2 story pensilcase inside that pensilcase, the bigger one, bigger than the artsy one of yours. Thank you for this video Minori it reminds me of my past haha. 🌷🍰 I'm from Indonesia, Hai from Indonesia🇮🇩

[@h0rriphic]

The first case brought back so many early childhood memories. It’s the exact sort of Hello Kitty aesthetic that was huge in the late 80s…Hello Kitty’s color pallet became far more pastel in the 2000s onward.

[@kerseykrewzoo]

We never had anything cool like this when I was in school. The closest thing we had was a Trapper Keeper but it was meant for folders and paper and had a few places for pencils/pens and 3 metal rings to keep your paper, folders and "binder add-ons" like zippered pencil pouches, dividers, pocket panels, etc.

[@DAZZY_GURL]

I had these kinda stationery at school, it was super fun. They were imported from Japan I didn't knew

[@kseniakondrashova2768]

OMG I am having a massive flashback from childhood, I had a similar one - it was pink, it had a thermometer, an eraser tray, and some scrolling details with dates! I remember the feel of it and the sound of the thermometer lid clicking! I would have never remembered it if not this video!!!

[@debleb166]

I have a pencil case like these that I got new from a bargain shop in Ireland this year. It has two compartments (one of them can poke out of the side so you can get your pencils without opening it!), a pencil sharpener, a calculator, an eraser compartment, as well as a space to put down your name and class number. All the special parts open with little individual buttons. It has a cool dinosaur print, but they also sell ones with unicorns or rainbows.

[@kalezuki9231]

These are so cool , I love that one doubles as a toy house / set piece for little paper dolls or just mini dolls in general lol & the Black one is a nice mix of "mature feeling" yet potentially "childish" at the same time

[@inhalehexhale]

omg you unlocked a memory for me. I used to own that exact hello kitty pencil box when I was a kid and completely forgot about it!

[@Skittl1321]

In the late 80s there were so many cool pencils cases like that with hidden compartments and all kinds of buttons. I always wanted one.

[@NikkiDeJonge]

I had one of these box style "flip" pencil cases in the late 80s-it was light baby pink (around 88 or 89) & it mutli colored hearts on it. A classic mate gave it to me. It had places for pencils & a compartment for an eraser.

[@christinapark6973]

I had a Snow White version of these pencil cases and I loved it.

[@kirstend9390]

The Disney store in the 90’s would sell pencil cases just like this! My friend had so many of them, my favourite was a Minnie Mouse one, the top was squishy (filled with glitter & heart sequins & coloured gel) I had a Mattel/Barbie one.

[@julieannefowler5768]

I think my favorite one is the 'artist' pencil case, but admittedly, I would be that kid who covers the outside in stickers. Now, as an adult I would absolutely also decorate with some stickers. If going by the others though I would go with the doll house. It reminds me of Polly Pockets in the best way possible. Nowadays I just re-use candy tins for my art supplies or any pouch that has space for a pencil, pen, and eraser lol. Thank you for sharing these stunning finds.

[@Verlisify]

No one I knew had pencil boxes like these in the U.S. in the 90's. This stuff is incredible

[@Sumerugeniusenjoyer]

I have this during my childhood. There's a tray on the back, a built-in sharpener, might as well as compass and basic calculator, and planner. The place where I put the pencils also has something to hold to keep them in place and a divider where I could place the eraser. I'm considered one of the rich kid in those time along with other kids that has fancy pencil case before. I missed those times. Hehe.

[@LisabettaMedaglia]

I had one of those when I was in Jr. High in the late 80s! It was more similar to the first one (the Hello Kitty one), where you press a button and different things pop out to reveal what they are from their hidden spot. The part where you put your pencils had loops in them, and the background of where the pencils rest, could prop up, so they kind stood up straight, but on a bit of an angle. Mine also had an old school thermometre in there (it was white, with the red liquid that measured the temperature). I used that thing all the time until it broke...but I loved that case :)

[@sarahross2441]

I had one like these as a kid. Loved them! A few months back I found one online and bought it. I was using multiple styluses (styli?) with different nibs and skins, etc. It has worked out really well. I’m thinking of buying a 2nd one for eyebrow and eyeliner pencils and pens. I stole the sharpener from the 1st one to use with those already. The 1st and the last on this video are so cool!

[@pams3887]

Growing up in the 90s in Malaysia, the pencilcases with the compartments that pop open or have hidden things were what the cool kids had 😆 I never owned one of those, but I was fascinated by them. Gosh, this brings back childhood memories 😄

I owned a lot of these fancy boxes when i was a child . I still remember we all were so facinated by these cool stationary products back then . Now i have simple cute unicorn 🦄 kit which i haven't change for last 4 yrs . I feel so nostalgia and old at the same time when i am just 17 😂❤

[@kitterzy]

My sister had a US version of the HK pencil box from the late 1970s to early 1980s. It had markers, the stencil you have, a protractor (yours is missing), an eraser, and a stylus to write on the “notepad”. I’ve been a fan of HK ever since my oldest sister bought me my first HK stapler in 1976 (I was only 6 yrs old and she was 22yrs) for Christmas. At 53 years old, I still have the stapler and a lot of other HK and Chococat items including my purse from Loungefly. I’m starting to appreciate other Japanese stationery as well. Glad to have found your channel.

[@monroeroams]

I always wanted a Pochacco case just like this when I was in elementary school but it was more expensive than just the regular boring pencil cases with one big enclosure. I love that you were able to find some gems and in great condition!!

[@littleblueorchid]

I just bought two pensile cases like the hello kitty one where things pop out form TJMaxx in the US as a gift for my 2 daughters as birthday present. So yes they still make these now for sale.

I had one of these in the late 80’s. It had Sanrio’s Tuxedo Sam on it. It basically had all the same features except it had a ruler and an actual thermometer with mercury in it.

[@kahvipaputyyppi]

I had similar pencil case which belonged to my aunt, it had a big box for eraser, sharpener on the side, storage for pencils on both sides, pockets for scedule or ruler, tiny mirror and kind of legs you could open and have the case stand on them.

[@katiepeterson2306]

These are so cool! My pencil case was a basic pencil pouch or a hard plastic box with no organization haha.

[@alifishies]

I've seen these types of pencilcases recently. I'd definitely beg my parents for one of these. I love the second pencilcase's print. I can imagine it being pretty annoying having to constantly remove pencil shavings, replacing specially made items and placing pencils, but the erasers would probably stay clean

[@miyabi-chanmi]

I had two or three pencil cases like these that were all Sanrio themed! My dad got one for me on a trip probably in '99 or 2000 and I fell in love. They were my treasures and I felt so cool opening up all of the secret compartments, this has brought back such sweet memories. ☺

[@maggie2451]

[@joharry946]

We had very similar things when I was growing up in New Zealand, but not with Hello Kitty - they had other characters on them. I also remember a tin pencil case I had, with a little girl character on it - I think it was called Tiny Candy, and it was old when I got it. My sister had a "Holly Hobbie" stationery set and it was very cute too.

[@turtleby]

i remember i had one of those pencil cases!! loved them and saw a lot of variety from other classmate's jaapanese pencil cases

[@qwertzuiopasdfish]

I was a European kid but I had one of these in the mid 90s, and it was absolutely amazing! I came across a bunch of knockoffs in the late 90s, but nothing came close to my original pencil case in grade 1. It was I think Sanrio, had Dancing written on it and 3 Miffy figures were dacing with dark purple background. It had one magnetic closure on top and 2 layers inside, you had to pull the top to reveal the bottom. I think there were just holes for storing pencils standing, and there was a little slot for timetable. While it had very little space, it was inspiring to make the best use of it! Unfortunately the top fell apart so I am afraid it was put in the trash.

[@AndrewZelenka]

I actually had the hello kitty pencil case in the early 80's. Also had the matching 3 ring binders. We had a hello kitty and friends store at the mall growing up.

[@tanmaywho]

I use to have a simillar one, the main quirk it had was a mini white board and a button which pops out a black marker aslo a sharpner like the first box you showed and 3 compartments. I thought it was really cool at the time.

[@LoveLaceLament]

I’m obsessed with stuff like these! The first Sanrio one made me giddy!! How fun!! The last one is insane and I freaking love it!!!!!

[@zengwenxin8402]

I had some of these pencil cases as a kid. They totally were distractions for kids for real. I remember flexing all these function and arranging where to store what during the class instead of listening to the teacher.

[@farzaanafisher6662]

These are so cute. The first one is definitely my favourite. Here in South Africa, my kids found some similar pencil cases. They have a couple that are similar to the first one. These have isolated spaces for a ruler, eraser, scissor and sharpner. All of these are included in the pencil case. Also has buttons that eject the items. One of these also has a pencil holder that can stand up.

[@ishanibhardwaj421]

I loved all the pencil cases especially first and last!! Its so cute to have a doll house in a box, so in free period you can play in class with your friends with a story made up would be so much fun.. I had pencil case like that which opened on both sides didnt have compartments but had a white board when we opened from the middle. So i used to kind of play-pretended to take my notes on it😁😁. I loved it so much but lost it somehow idk
