This is a kit for a Lego block secret device. The book is mostly unopened, and the included parts have not been opened either. However, most of the blocks are missing, and there are only 5 left. They've gotten mixed in with the children's Legos, so I haven't thrown them away, but I will try to find them. - Model Name: Karakoro Pitan! - Contents: Lego blocks, some missing - Description: Secret device made with Lego blocks - Target Age: Children - Ranking: Amazon Ranking Best Seller #1 Thank you for looking.
