I have kept this item in a dark place since I purchased it, and I have never used it. Please understand that this is a used item before purchasing. There are three pockets inside (one with a zipper) and one zippered pocket outside. The size is as follows, although it is measured by a layman: Width 35 * Height 24 * Depth 15.5cm Shoulder strap length 55~104cm Material: Polyester
