What is Brick Bag Inventory?

Brick Bag Inventory is a free tool that shows you exactly which LEGO parts belong in each numbered bag of a set. Instead of sorting through hundreds of loose pieces, you can look up any bag number and see every part it should contain — with quantities, colors, and part images.

How are bag inventories created?

Each bag inventory is built by carefully following the official LEGO building instructions step by step. At every step, we record which pieces are used and which numbered bag they came from. The result is a complete, accurate list of every part in every bag.

How accurate are the bag inventories?

Very accurate. Because inventories are created by following the official instructions step by step, every part is tracked to its exact bag. Since this is done by hand, mistakes can happen — if you spot anything wrong, please contact us so we can fix it.

How can I request a bag inventory for my set?

Search for your set and open its page. If no bag inventory is available yet, you can submit a request. We prioritize sets with the most requests and will notify you by email once it's ready.

Is Brick Bag Inventory free?

Yes, completely free. Searching sets, viewing bag contents, and exporting parts lists costs nothing.

A BSX file is a BrickLink-compatible XML file. BrickLink sellers can export a bag's parts list as BSX and import it into tools like BrickStore, making it easy to list individual bag contents for sale on the marketplace.
