This is an authentic product. It has not been cleaned, so please wash it before use. There are scratches, marks, and dirt from use. The condition varies. Please understand that this is a used item before purchasing. Due to the thickness, this item will be sent without bubble wrap, in a clear plastic bag and an envelope for simple packaging. I am also selling other LEGO products. If they can be shipped together, I will discount the shipping cost. Details are in my profile.
