Missing pieces, returns and warranty

A missing brick at step 12 is the worst. Here's what to do.

1. Check the bags again — small pieces hide in the folds and under the instruction booklet.
2. Open your order page at the partner store you bought from and choose the return or replacement option for the set.
3. For warranty questions about a set, the partner store's order page is the right place too — they have the purchase details.

We can help you identify a piece or a set number; write to the builders' desk with a photo of the page in the instructions.
