How to Refill Pentel Color Brush Pen

Here's how I refill my Pentel Color Brush Pen. For black, I use Rotring ink. If you want colours, you can try Dr. Ph. Martin's Hydrus Watercolor.

Thanks for the video, but a warning to newbies like me: DO NOT throw away the inside tubes, the ink flow is crazily wet without it!

[@candyandfruitc7496]

i made this mistake and i cant find the stopper ;-;

[@quetalsam]

Thanks for the advice

[@TheHeavenlyBuddy]

“The price for this is 65...” Me: D: “... cents.” Me: :D

from 2016 video

[@visualkandi]

Brilliant idea! Save money and the environment, every fill is one less pen in a land-fill :-) Thank You Teoh

[@Jojoosborn]

Great tip thanks

[@teamrabbitalec]

You turned it into an actually useful Fude Pen. I have been searching for a Fude Pen that is more like an actual brush but has the convenience of a pen. Good Job.

[@saionjisan]

What is a fude pen?

[@Ucceah]

fude brushes or pens are made primarily for writing. they typically have a relatively short and springy brush tip, allowing for a lot variation of line width. where those ment for drawing/painting have longer bristols, and tend to be easier to control, doring long strokes, because they arent as sensitive.

[@moosequeen]

Thank you so so much for this! I even tried figuring out with my entire family but we could not find an opening, until i saw your video. the pen is so craftily designed, thank you again for sharing this!! 🙏🙏🙏

[@Cyd1057]

Whoa! Great info, Teoh! I hate throwing away those empty pens. Thanks for sharing your resourcefulness. Very clear and great videography, as usual, too!

[@leahsandow9300]

Absolutely loved it, ....who knew there was so much to learn about just one pen!?!!....Great video, I particularly appreciated the ''straight forward approach", and you tell it how it is! Well done!

[@Cyanbuns]

Great advice, I removed just the middle barrel(with the red cap on one side) as the ink flow was quite slow and it works just as I wanted now.

[@ravis323]

Thank you so much mate! we need more people like you who come with great ideas! More power to you!

[@teohyc]

Thanks :-)

[@christopherlucente2514]

Great video, very helpful, thank you so much for all of your content! I've been subscribed and watching your videos for years now, and they are always very informative and a pleasure to watch. Keep up the great work!

[@MariaRamilPersonalPage]

Thanks for this tutorial. I tried the color brushes but found the ink too slow-drying. I decided to refill mine with water instead and they are fantastic as water-brushes. Better than my Pentel water brushes, as the flow is more frugal and can be used almost dry (you need to press hard to create washes) . Shame the barrel is not transparent but the 6.5ish ml capacity lasts longer than you'd think.

[@amyc9984]

Wow!! Thank you so much for this very clear and informative video!! I’m definitely going to refill mine when the ink runs out!

[@milmil3642]

I use this pen a lot! The refill cartridge itself is not chap at all if you buy many times. This video will help me so much of my expense. Thank you!

[@melsgalleria]

Thank you so much for this video! I hate throwing out perfectly good pens when they just need more ink.

[@tpfernandez]

You are doing the lord's work here. Thank you so much for your hard work.

[@sketchbig]

Teoh, you have saved me. Thank you for taking the time to make this video.

[@iacoposeri3420]

Man I was looking for this hack for ages! Thank you so much!!

[@SL33P-WALK3R]

This will save alot of money over the yrs. Thank you so much!

[@kennethbigboi8913]

I just got myself this fude pen i have been searching for a vid like this thnks!

[@adethdeguzman6085]

Now I got the answer of how to make this pen brush release more ink. Nice!

[@ivanav.3136]

was gifted the very fine variant of pentel fude and being a noob i had to google the basics. this vid came up and answered most of my questions and the comments here are interesting too. thanks!

[@artistmedea]

Just told the Japanese merchant about the two major problems with these brush pens. Seems the Japanese guys still are not fully aware of the plastic problem Worldwide! Thanks for the amazing video! Made my day!!!

[@SuperKingbunny]

they are, but company needs to make money with ink, they cannot survive with just pen sales

[@snoozerelli]

Thank you, Teoh for posting this! this is just what I need! :D

[@kelleyphung]

thanks! I was wondering if you could refill the cartridge. this answered my question. very helpful

[@CyndraMystic]

Thank you for sharing your findings, this is super helpful to me

[@gene7788]

I recommend using Daiso Sumi Ink, it’s a thick India ink for Japanese calligraphy and the dude brush pen is also sometimes used for Japanese calligraphy

[@SNEAKchannel]

very flow ink! great!

[@4TUNECHINGSAN]

Many thanks for your film I have two of then and they went out of paint and now I can refill it .It was great help!!!!

[@shiro9716]

Just tried it !! It was amazing ! Thank you

[@timtapp5931]

Great video. Just ordered the extra fine and medium. Hopefully this method will definitely extended the life of the pen, and be less wasteful.

[@Blagagongaa]

You've got a new subscriber this video was really helpful, thank you !! And I like your other pen reviews

[@teohyc]

Thanks (ᵔᴥᵔ)

[@hingginchu]

Very thorough instructions. Thank you.

[@liviuaileni]

Thanks, man, great tutorial!

[@cloeywalker4811]

thank you i will try this ;D i just ordered the pen for my lineart! ty when it runs out i will try this :D

[@humanharddrive1]

Glad to know these can be refilled at home. Not paying for these cartridges for as much as i'm using my brush pen

[@randommortal3383]

You just saved a life! Thank you so much.

[@jasonmullins6638]

That was a fantastic review sir! so..if you want generous ink flow..leave that tube out..otherwise fill it up and place back into pen..I've got a couple of pens and this will save me some money...thanks Teoh!

[@teohyc]

+Jason Mullins Thank you 😃

[@josephbarahona4516]

This was so useful! I actually was trying to refill the brush not knowing that there was a seal and made a big mess on my desk😹😹😹

[@jeanmc3]

Thank you Teoh...for this and all your great videos You are amazing

[@teohyc]

+jeanmc3 Thanks 😬

[@iggzistentialism8458]

Thank you so much! Just what I needed.

[@sumairah4507]

Thank you very much. I was lost as some brush pens are required to be filled with water. Very helpful. God bless.

[@SerenaLewis]

Very helpful - thanks, Teoh!

[@petitio_principii]

Thank you so much! I have a Kuretake pen, which despite looking pretty much identical, apparently has somewhat different, simpler mechanisms inside (it hasn't that rotating disk ink stopper, unless I somehow broke it in my previous attempts), but otherwise the same procedure works. That outer stopper really just looked like it was a single piece with the barrel, I couldn't believe I never noticed, but it was really a separate piece! My failed dumb attempt was just trying to stick a syringe without removing the inner cartridge before, which I didn't know exist, I thought it had just some sort of sponge inside the outer body/"barrel". That "works", but the ink flow becomes absolutely torrential and uneven, actually dripping, totally wrong for me. Most of the ink was ending up in the outer cartridge body, more or less like a water brush seems to work (guessing from pictures). And the inner cartridge was not even connected to the brush anymore, but stuck in the rear/upper end of the outer body. Filling the inner "double" cartridge has apparently restored a proper ink flow, more restricted than how it was before, allowing me to get more line control and not worry about ink drops.

[@ohmthepoet8428]

So you do stick the syringe into the little barrel inside? He didn't specify exactly what he injected the ink into and I only saw him put the stopper back on so I'm assuming the barrel was inside, but wouldn't you have to reconnect it ?

[@MattiasWirf]

This is a bit late to comment but, the "cartridge" body is quite wide, maybe one can make do with an eye dropper (where I live there seems to be a hazzle to get a syringe). I'm going to try when the ink included runs out. I'll try refilling it with Platinum Carbon Black I think.

[@Hegottalent_]

Thank you so much for this vid, I have the same exact Japanese pan you have company and everything,and I didn’t want to spend more money buying another ink brush

[@DonisAnimation]

Thank's man, very helpful video, as always... Have a good day, and good luck!

[@teohyc]

Thank you. :-)

[@tutorialgirlhere]

Thanks for the video. I was wondering how to do this, because it's expencive toy after a while....I want to use watecolor based ink. Just need a needle first.

[@edinstead]

Thanks for all of the good reviews you do. A couple of things, the tubes inside have nothing to do with the ink flow when you're using the brush to draw or write. That's controlled by the the white cylinder at the base of the brush. I suspect that they put the tubes inside so that people who don't really know how to use the pen do squeeze way to hard and squeeze way to much ink on the bristles. If you know how hard to squeeze then there's no need for the tubes or little valve with the pie-shaped cutout. I find those parts can get gummed up any and cause uneven squirting, causing flooding. I cut the refill plug right off right after where it supports the threads and take the pie-shaped valve right out. Works perfectly every time! The only problem I have is that the tiny cylindrical valve near the base of the bristles will get clogged.

[@rodolfoperez325]

Thanks you Teoh, I thought it was sealed shut. Great tutorial.

[@BT-nn5wr]

Hi Teoh! Nicely explained! A very useful hack!

[@teohyc]

+B Thomas Thanks 😁

[@edlong7333]

Hi Teoh, I enjoy watching your videos, especially the pen reviews. I would appreciate seeing a review of the Pilot Perera fountain pens. Thanks & keep up the great work, it helps a lot.

[@teohyc]

+Ed Long I've a text review at www.google.com.sg/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwjngtDS7evQAhXMp48KHTq_APcQFggbMAA&url=http%3A%2F%2Fwww.parkablogs.com%2Fpicture%2Freview-pilot-prera-fountain-pen&usg=AFQjCNHTWdHO4_mIZUhlXrd_wtlhNOFVEA&sig2=gHRZbexu18AWI8Ty4nGrIw

[@potato3d372]

I've refilled "Zig Art & Graphic Twin Brush Pen" (black) with ZIG Sumi ink 60, it works just fine, almost a year passed from refilling

[@vulnerablerummy]

thanks for info, are you still using it?

[@potato3d372]

​@@vulnerablerummy sure, brush tip haven`t damaged yet :)

[@colinreid325]

Thanks for this refill info

[@tanobonfanti7279]

thanks man really helpful

[@edwood9321]

I love you for this!!!!

[@vaderetro264]

Very good instruction video, thank you.

[@cmcasadoiro]

Very useful, thanks!

[@reyalara5595]

Great videos, very insightful :D

[@tonptrs]

Great idea. I go for it🤗

[@noahhunt8575]

I actually like the default ink flow, I kinda of like the messy and sometimes un-inked lines.

[@harrisonlee9539]

Hi, would you recommend washing your cartridge before filling it with new ink or is that unnecessary? Would I also mess up the ink flow if the cartridge wasn't completely dry? Thank you.

[@thomass.5360]

Brilliant video! Will this ink also work with a pentel aquash waterbrush or a fountain pen?

[@teohyc]

Not sure about that. I've a friend who tried and says that it leaks. It's worth a try though, at home, in case it leaks in your pencil case or bag (no!!!).

[@veloetstylo]

Useful hack, thanks.

[@timeconstrained2400]

so let me be clear...is the whole top part of the pen a cartridge which you buy for $2.40? Ive never seen a cartridge that is designed as the complete top part (body) of the pen...usually it's just an insert into the pen body. Great tutorial but my old eyes will have difficulty with the process. 2 other things -this pen has reverse threading to open (clockwise opening) - I was tightening the darn thing thinking it was typical anti clockwise opening. The other thing - the cartridges are about USD7 in Australia - crazy. Also when I first start using the pen do I press the cartridge to get the ink flowing or just face the nib downwards and let gravity do the work.

[@matteogenoveffo]

best video ever

[@diegodossantos7656]

That's helped a lot, man!!! Thanks :)

[@teohyc]

+Diego dos Santos (Bhradokk) Cool 😀

[@debla6141]

hello! thanks for the great video i found it really helpful :) i was just wondering, could use india ink to refill this brush pen?

[@teohyc]

+Debla India ink may clog. I use Rotring ink

[@gu2308]

Hi , I have a question. Is it possible use a acrylic ink inside ? Thank you

[@pablobarrios7681]

hi teoh! ive been refilling my brush pens with black star ink, but i tried switching to rotring since its cheaper but the bottle i bught seemed to have a solid black block at the bottom and clear liquid at the top, is this expired ink? it also isnt waterproof for me, thanks for the inspiring and helpful art content over the years

[@bernardhornblower3667]

Thanks so much for this

[@juliearmymom7807]

I do weekly chemo shots and B-12 shots, and my husband mixes e cigarette juice, so we have bought needles before. Sometimes, especially blunt tip, they will give you for free at the pharmacy. Another great place that is cheap is the Tractor Supply Company (also has dirt cheap quality pet food).

[@samreenart]

Informative video! Thank you. I have a question though. What's the difference between this brush pen and the Pentel Pocket brush pen? I already have the Pentel Pocket brush pen and I love using it. But I was thinking of buying this color brush pen as well.

[@teohyc]

Pocket Brush Pen is waterproof. Color Brush Pen is not waterproof. Color Brush Pen has larger ink capacity and more if you remove all the unnecessary things inside the cartridge.

[@samreenart]

Oh, thank you so much for the information.

[@niwu5218]

Thank you sooo much!!!

[@josselin165]

What ink Can I use that looks shiny and that is thick like the original that pentel has?

[@jjkanuck628]

I Really enjoy all your journals and sketching. Your excellent at it.. great works If I refill Pentel brush pen can I use PIGMENTED INK or just regular ink.. tnx

[@teohyc]

+J J Kanuck If you want waterproof ink, you can use Rotring. If not any fountain pen ink will do, and you have access to different colours too.

[@piefjep9508]

Thank you for your review. I found a very good deal on a set of 4 Rotring Rapidograph pens. One thing that is stopping me buying this is the non-refillable cartridges. Do you know weather they really can't be refilled or is there a trick like with these Pentel pens? (I know the Isograph pens are refillable, but I can't find a good deal on those.) Thank you.

[@PaulaBean]

You can indeed refill the rapidograph cartridges with a syringe and needle. I suspect manufacturers make their cartridges hard to refill so they can sell more cartridges.

[@karolus28]

finnaly ink that I can buy in my area

[@mr.boombastic170]

can you use parker quick ink in brush pen

[@ugabuga2586]

thank you so much!

[@JoanaCristinaArte]

Thank you so much for this video!! I got several of these for the colors but didn't like the quality of the ink, not one bit!! they reactivate with water and it would ruin my work, I got them to line the sketch to color later with watercolors. Now I'm replacing the ink with others that don't reactivate. Thank you!!

[@teohyc]

Check out these inks www.parkablogs.com/content/waterproof-fountain-pen-inks-drawing

[@lordwander]

thanks for this video, it's very helpful. I am wondering if you have ever tried the Kuretake Zig CocoIro pen? if so do you know if we can refill that pen with our own ink or do we have to buy the refill tube/pen? because I want to get one but the refills are kind of expensive so I just want to know if there is a way to cut cost on refills. thank you.

[@teohyc]

I've not tried the CocoIro before. Perhaps in the future.

[@PuchyTats]

excellent video!

[@teohyc]

+Puchy Tats Thanks 😊

[@TheMeltedMan]

If I were to use rotring ink on a drawing sketchbook, would it feather if I made large brush strokes?

[@teohyc]

It should not feather. But paper matters.

[@scottyboy0321]

Thank you!

[@davidbowtie4480]

Thank you for this video! Have you ever had the same problem as me? I have red and black pentel brush. The Black brush dries out very often. I push the black ink and the it flows but later i need to push it again. i need to do it so many times but there's no problem with the red brush, i can't remember the last time i squeezed it.

[@teohyc]

Could be a problem with the cap that is not secured. I've a black brush pen for months and it still works fine. Or try putting the brush with the tip pointing downwards as you store it away. But ink flow for these Pentel Color Brush Pens aren't very good to begin with.

[@K1DWOLF]

Thank you brother

[@amirbabaei7048]

Thank you sir .

[@arncj18]

would appreciate a refill tutorial on the Pentel Sign ultra fine brush also

[@bayusabi]

Oh yes, i really need to refill my pentel sign artist brush pen.

[@CarlosRamos-gq2hs]

fantastic video!!! i was looking for something like this! i have a question what ink is better for this kind of pens, any technical ink like for rapidograph pen( rotring, staedtler,dr phil) or yidege?

[@teohyc]

+Carlos Ramos Those should probably work.

[@germaicanlady]

Cool! Thanks! :-) BTW: Lindsay The Frugal Crafter mentioned you today when someone asked which watercolour to use in her live stream.

[@teohyc]

Cool. I must watch that video! Thanks. Heheh

[@Nahibs]

Very Helpful! Thank you. so ... can refill with other nakim colors?

[@teohyc]

There should be no problem.

[@primeflux9682]

Thanks for sharing this 👍😃

[@shanewells9647]

So if I wanted to have a slower flow and put those tubes back in would I still fill the black barrel with ink and put ink in the other tube as well?

[@teohyc]

You just refill it as normal. You don't have to fill the inner small tube.

[@dylandepinto6182]

Does it matter what ink I can refill the pen with ?

[@littleripper312]

Hmm, I'm thinking the Aquash pens might be easier to use and refill for my coloured inks. I wanted to make brush pens out of my Dr Ph Martin Bombay coloured inks just as a cheap set of colours for my sketchbooking and doodling. The Aquash pens are not good for lineart stuff because the ink flow is too much but it might be good if I just colour with them. Or I guess I could buy some more pentel pocket brush pens.

[@visualkandi]

Just a thought...Maybe you could make the inner tubes ink hole a little bigger? Perhaps that would increase flow, give more options for inks (Sumi, nano/large particle and other more problematic liquid based media) and decrease the risk of leakage when capped?

[@teohyc]

+Simon Mirfin The hole inside the stopper is actually quite big. Ink should not be able to clog there. Possible clogging area is probably within the grip section behind the brush.

[@gabgame300]

amazing

[@anilkumarn8879]

Thanks for sharing.

[@cigimon4]

do you know if this cartridges can be used on the aquash waterbrush? I have the waterbrush and the individual cartridges screw system looks similar but I've never tried

[@teohyc]

+NotAName They are not interchangeable

[@kairabibhattacharya6564]

Thanks a lot
