You are purchasing a built model. This model was built with model glue. I will package up very securely but due to the nature of this item, some pieces may need to be reattached once received. If upon arrival there is more than a few minor repairs needed I would absolutely work with the customer to make it right even if that means a full refund. I want to state that because these items are very fragile and small pieces may come unattached and need to be reattached. The model moves freely and the motorcycles go around when the gear in the bottom is turned. Don't buy if you don't agree. Thanks for looking and appreciate your business.
