I used it only once and have kept it stored at home ever since. There's a brown, frayed-looking area on the back, but it was there from the beginning (when I bought it new). It seems to be due to the material, which is a hemp-like fiber, giving it this kind of color. The inner pockets are deep and divided into two. Height: 25cm, Width: 33cm No depth/gusset. Color: Beige
