Authentic product. Since it has not been washed, please wash it before use. There are scratches, marks, and dirt from use. Please understand that this is a used item before purchasing. Due to the thickness, it will be sent in simple packaging. I am also selling other LEGO items. If you purchase them at the same time and they can be shipped together, I will discount the shipping cost. Details are listed in my profile.
