How was this bag inventory created?

This bag inventory was built by following the official LEGO building instructions step by step. At every step, we recorded which pieces were used and which numbered bag they came from, resulting in a complete parts list per bag.

What does each bag contain?

Each numbered bag contains a specific subset of the set's total parts. By selecting a bag above, you can see every piece it includes — with part images, color details, and exact quantities.

How can I export a bag's parts list?

Click on a bag, then use the export buttons in the toolbar. You can download a PDF for easy reference, or a BSX file — a BrickLink-compatible XML format you can import into tools like BrickStore.

Why is there a bag 0 that is not listed in the instructions?

We use bag 0 to list all parts that are outside of numbered bags, such as sticker sheets or some larger parts that are often not in any bag but directly in the box.

What if a part seems missing or incorrect?

Since inventories are built by hand, mistakes can happen. If you spot anything wrong, please contact us so we can review and correct it.
