Height 27cm, Width 30cm, Depth 15cm It has a depth, so it can hold a lot of luggage. The shoulder straps and the bottom are adjustable. One inner pocket. I have used it almost every day for commuting for about 2 years, and there are scratches on the plastic parts and the fabric (on the bottom). Please refer to photos 4 and 5. There are no scratches on the plastic on the top (see photos 6 and 7). I think the condition is clean considering I used it every day. Please purchase only if you understand that this is a used item.
