This is a Cledran tote bag. It can fit A4-sized notebooks and can also be used as a backpack. The backpack straps are adjustable. It has a drawstring closure at the opening, allowing it to be cinched closed. I bought it new for commuting, but I no longer need to carry documents due to digitalization, so I only used it for about a month. It has two pockets inside and a pocket with a button on the outside. There are no major stains on the outside or inside of the bag, but please understand that this is a used item. There is no significant deterioration of the cowhide leather parts when used as a tote bag (see photos). The materials are nylon and cowhide leather. - Color: Beige - Material: Nylon - Design: Tote bag, backpack, 2-way - Straps: Adjustable shoulder straps - Inner pockets: Yes
