I bought this a few years ago, but it didn't get much use and has been in storage. While it has width and depth, it lacked thickness (gusset). The main pocket has internal dimensions just right for a CD case or a small tablet, and the sub-pocket, which is opened with a magnetic flap, is almost the same size. There's a buckle on the back (to which you can attach straps for the shoulder or waist). There's also a vertical strap, presumably for threading a belt. There's some aging on the exterior, such as color changes on the corners, but the buckles, snaps, and magnets function without issue. There are no tears inside the pockets.
