The packaging process is the one that I find most fascinating, because each set has so many different components. We never get to see where or how the instruction booklets are printed; are they printed off-site or on-site? Do they ever run out of instruction books and have to delay the entire production line? This is also the step where machines are currently being swapped out for recyclable paper bags, replacing the single-use plastic bags. I would love to see where the paper bags are made. I also wonder how many different sets a LEGO packaging facility manufactures at one time, and if all the factories make all the sets, or some facilities specialize in certain sets. Do they spend an entire day (or week, or month) just packaging a few set until there is a huge inventory to ship out, then switch to different sets, do they have one assembly line for each set, or do they vary how many assembly lines are dedicated to each set based on demand? What do they do with canceled sets that were already in production, like the Technic V-22 Osprey or Overwatch 2 Null Sector Titan?

Great video! I'm not a hardcore Lego guy but I've played with them my entire life. I'm always amazed how I've never bought a single set that was missing a piece. Not once. The level of quality control in Lego is second to none.

[@AK.__]

I had one or two sets, where the colour of piece was either incorrect in the manual or incorrect in the set: dark gray instead of black. Otherwise all was perfect for years.

I am usually impressive with the quality. However, between my husband and my daughter, we got 8 new Lego sets the last few months. Two sets had a missing piece and another set had a piece that was crack/smashed at the corner. The set with the problem are pretty large sets. Lego does have excellent customer service. We got the replacement piece in a week.

[@scoutgaming737]

I love how they invite kids to play with the sets

[@DeadlyPlatypus]

Huh. I always just assumed they gave you "extras" of the smallest, most commonly LOST pieces just in case you lost one. But this explanation makes way more sense given the seeming randomness of the pieces and their numbers.

[@kailahmann1823]

I guess, having spares for the customer is a positive side effect. And no, there is nothing really random about them - in fact these pieces are very predictable, as every mold either comes always as a spare or never. Also there are a few rather light pieces that don't go as a spare (like the infamous blue technic pin) for some reason and in large sets, you may find repeat spares in later bags. And if you don't have one spare left for a mold where you'd expect it, that's one of those rare packaging errors they are buffering.

[@nils920]

Meanwhile in a LEGO City family home: "Dad, where do babyfigures come from?" "Son, it's time you finally learn..." *shows this video*

[@kentslocum]

Setting the price before designing the set makes sense for smaller sets and themes, but it results in big problems for larger sets like the Tabletop Football set and the UCS Hulkbuster, where the sets are unnecessarily padded to meet the price point.

[@Immortalcheese]

i notice this sometimes that some sets seem to have artificially increased their piece count. like a step involving placing two 2x2 brings side by side instead of one 2x4 brick, which increases the piece count and justifies a higher price.

[@PlutoniumBoss]

What I'm really interested in is a closer look at the double-molding process some LEGO elements have these days. I've never seen anything else quite like it.

[@thrillhouse4151]

The only time I had pieces missing from a set there were two pieces included that were nowhere in the set at all, one was a small window which was kinda cool. Thankfully LEGO will send you replacements if you’re honest about it. I really like the bag the replacement pieces come in, it’s labeled like a set.

[@JOlivo94]

I always thought the extra pieces were in case we lost one. I always wondered how they decided which ones were most likely to be lost. 😂

[@beelzemobabbity]

I think its an added bonus, since small pieces are the most likely to be missing and go missing

[@tha_dealler4811]

5:59 old ones were made in ABS but in 2015-ish they swapped to PVC which is still good but less prone to break like old Bionicle parts which were made in ABS

[@Blobbyboi986]

They are currently changing them to a recyclable plastic

[@Michael-dj6pd]

The infamous brittle brown pieces

[@massimookissed1023]

Lego's own website says most bricks are made of ABS. ABS is almost infinitely recyclable. The main change was clear pieces used to be polycarbonate, but are now a type of transparent ABS, which doesn't require different molds (unlike polycarbonate) but does scratch more easily.

LEGO is probably the greatest toy ever developed, playing a part in the childhood of many a person out there. An extremely creative toy that encourages thought and experimentation in the developing mind. Having actually worked for this company some years ago, much as I found it interesting to be part of the LEGO world it was also an eye-opener ..... The Danish company are heavily into psychology and the their angle is that everyone within it should be a big happy family... Nice in theory (if not a little creepy and 'Stepford') but sadly didn't actually work in the UK. Another little known fact about this company is that they NEVER fire anyone..... They just make your life so difficult that you just resign (no HR to speak of back then). Having been part of the original UK LEGO team, it became apparent that their magic formula didn't translate particularly well over here, mainly because their selected management were completely unsuitable and made some staggeringly bad decisions with regard to staff employment - Narcissist's and bully's do not make great co-workers! It was so bad that I left the company on my own terms. It great shame really, as it soured something that I had a great fondness for. LEGO have now sunk to deeper depths by heavily relying on income from licensed Disney models at ridiculous prices....

Great job on the video, too!

[@lego_minifig]

3:00 I have a similar setup at a much smaller scale. I have my entire collection sorted by piece in around 30 tackle boxes and a few bins for larger or more common pieces. I have custom labels printed on each box and have them numbered with a master document showcasing all the pieces. Its a nightmare to disassemble sets/creations. I hated it when I was younger as it stifled play. Now that I am older I appreciate it as it makes it easier to reassemble nostalgic sets in my collection and far simpler to find specific pieces when building a stop motion set.

[@kailahmann1823]

For precision of the machinery it's often stated Lego is an even more demanding customer than medical or military.

[@thewhitewolf58]

Which military. I know in the usa military buys from the lowest bidder so military grade means barely functional.

[@massimookissed1023]

The size tolerances must be very demanding. Too tight and they won't fit, too loose and they'll fall apart. I recently heard that polycarbonate shrinks more than ABS, so clear pieces needed their own special molds for standard parts to allow for extra shrinkage. One reason why Lego switched polycarbonate for transparent ABS.

[@mattraviler8500]

Fun fact the building that where they do there brainstorming has a maximum security protocol. "If a visitor is spotted with eyesight. All of the windows closed that are made of steel. All the doors are locked and blacked out" after some time the building will unlock....

[@tfoxsw7652]

One of my last sets I got came with a extra 2x5

[@Madcat0]

I wonder what are the requirements for a new piece to be approved for production. I mean, a new piece requires a new mold and storage and it's going to be used in just one set until the designers use it again in the future so i guess someone has to approve it or tell the designer to use a different solution.

[@thewhitewolf58]

Probably like the lego ideas set where they thing it has to be stable and popular enough to justify the cost. Though i feel that it would just have its own temporary machine to make 10,000 to 50,000 sets.

[@massimookissed1023]

I suspect there are many deciding factors. Can they make many in one mold, or is it a large piece that can only fit one per mold ? Is the new set predicted to sell enough that the new piece will cover its cost with just this set ? Or ... Does the proposed new piece have other possible uses ?

[@thewhitewolf58]

I always wondering if lego sets were designed physically or in a custom cad program. Thankyou for answering that. I guess when it comes to things with alot of small cheap universal parts physical is best. Though i do like the idea that lego is one of those toys that you dont really have to grow out of if your creative. True action figures have an age limit because they are usually based on a tv show made for kids but lego sets are 3d pixel versions of model sets thats only limit is your wallet and creativity.

For me as now adult who loved legos as a child, it’s all about unique parts. If a set does not have unique parts in most cases it’s not worth buying cause it can be made just looking at a picture of it. But sets with unique parts are always high demand. Especially unique canopy or colored glass wall pieces. The biggest disappointment has been not being able to get certain parts in quantity outside of certain sets for unique building opportunities.
