Invest once. Save time forever.
Our "Brick Bag Splitter" is not a commercial product, but an open-source community project and a new mindset for LEGO® sellers. Structurally dismantling a set into its original bags once will save you massive amounts of time, space, and stress for every future part-out.
The old vs. the smart method
Anyone who has ever parted out a large set with several thousand pieces knows the problem: You export the entire inventory from BrickStore, dump the bags onto the table one by one, and begin the endless matching process against the gigantic master list. This is error-prone, takes up an extreme amount of space, and is mentally exhausting.
Instead of fighting the chaos of the complete set, we use the structure LEGO already gives us: the numbered bags. With our tool, you take the time just once when parting out a new set to log which parts go into which bag.
The result is a small, exact inventory file for each individual bag. From this moment on, the entire workflow changes for you – and for anyone you share these files with.
The benefits in detail
Why it makes perfect sense to do this initial work. The effects when parting out the same set for the second, third, or tenth time are massive.
1. The Space Problem
The Problem: When parting out a 2,500-piece set with 400 different lots the classic way, you theoretically need 400 sorting trays on the table at once. A normal desk isn't big enough.
The Solution: A single build-step bag usually contains only 30 to 50 different lots. Because the split files tell you what to expect, you only need 30 to 50 trays. You sort the bag, put it away into your main storage, and your desk is completely clear again.
2. The "Where was that again?" Effect
The Problem: In bag 1 you find black 1x2 bricks. Hours later you open bag 12 and there are black 1x2 bricks again. Now you desperately search through a sea of hundreds of trays for the right one. This eats up time and margin.
The Solution: You stubbornly work through a short, closed list. There is no more matching with previous bags. You pack the part, save the small BSX file, and the process is physically and digitally complete.
3. Find errors before you despair
The Problem: At the very end of the set, BrickStore tells you: A red pin is missing. You've now sorted a massive mountain of plastic and have no idea in which phase the error occurred. The search is almost hopeless.
The Solution: Each bag is a self-contained system. If a part is missing when checking off the list for bag 3, you know with 100% certainty: The error must be somewhere on the table or in the still half-full bag 3. You correct the error in seconds.
4. The mental hurdle drops
The Problem: Parting out a 4,000-piece set is a marathon. If you get tired in the evening and have to stop, you leave a confusing mess on the table.
The Solution: Parting out is divided into extremely small, satisfying stages. Only have 30 minutes tonight? No problem. You only process bags 1 and 2. Afterwards, you feel a sense of accomplishment and have a completely empty desk for the next day.
Conveyor Belt Mode (Scaling)
The method really shines when you part out new goods not just once, but three, five, or ten times. Here, the prep work turns into pure speed.
Pure predictability
Before you even touch the set, you look at the file and know: "For bag 1, I need exactly 34 trays." You set up those 34 trays. No surprises, no sudden lack of space.
The Muscle Memory Effect
Instead of completely dismantling 10 sets one after the other, you open bag 1 10 times in a row. After the second bag, your brain blindly knows where the tray for the black brick is. You enter a flow state.
Giant sets, minimal space
Parting out five UCS sets simultaneously would normally require half a warehouse of workspace. With the bag method, your space requirement on the table always stays the same – you only need space for the current bag.
Uninterrupted logistics
Calling it a day right in the middle of mass parting out? You simply finish the current bag across all 10 sets, put away the (now very full) trays, and start relaxed with bag 2 the next day. Everything stays extremely tidy.
One for all. All for one.
This concept works best as a community project. If Seller A takes the trouble to map the new Star Wars set, and Seller B takes care of the new Harry Potter set, both profit massively in the end.
