This is a slim document bag. Size: 26 x 40 cm It opens with a click from the clasps on both sides when you spread it open, and closes with a snap. It does not have a zipper. I'm not entirely sure, but I think it's a leather product. It has a divider inside and a pocket on the outside. The AMSA logo is on the lower right of the front. It is new and unused, but it has been stored for a long time in a plastic bag. Please consider this before purchasing.
