Sort your LEGO® parts back into their original numbered bags and experience every set the way it was meant to be built — again and again.
A LEGO set isn't just a model. It's an experience — opening each numbered bag in sequence, building section by section, exactly the way LEGO intended.
BrickBag lets you have that experience again and again.
We built BrickBag because we needed it ourselves. After disassembling sets and storing them, we realized there was no way to sort the parts back into their original numbered bags — the data simply didn't exist anywhere. So we built it.
Our bag-by-bag parts data is extracted directly from official LEGO building instructions. Every part, every bag, every quantity — accurate to the original box contents.
RELIVE THE BUILD
Sort your parts back into their original numbered bags and experience your set exactly as LEGO designed it — from Bag 1 to the final piece. Whether it's your third build or your tenth, it always feels like the first.
FOR COLLECTORS
Restore any set to factory condition for proper storage, display rotation, or lending to a friend. Protect your investment and keep every set rebuild-ready.
FOR RESELLERS
LEGO sets command significantly higher resale prices when parts are sorted back into their original bags. BrickBag gives you the reference to get there — and a PDF to include with your listing.
FREE FOR EVERY SET
No purchase needed to research any set in our catalog. Every set page includes bag and piece counts, direct links to Instructions, BrickLink, Rebrickable, Brickset, and LEGO.com, plus live market value data showing average prices and what sets are actually selling for on eBay. BrickBag is the fastest way to research a LEGO set before you buy, sell, or sort it.
CHECK MODE
Designed for the sorting table. Work through each bag one part at a time, tapping as you find each piece. Completed parts move to a Found pile automatically. Progress saves between sessions so you can sort at your own pace.
PDF EXPORT
Generate a printable bag breakdown for any set. Keep it at your sorting table, pack it with a resale listing, or store it with the set as a permanent reference.
