I used this bag thoroughly for all three years of high school. *30L I used it for commuting to school, so there are scuffs on the corners, stains, scratches, and wrinkles. Please check the photos. I cleaned both the outside and inside easily. It's made of durable material, so I think it can still be used for a long time. If you are looking for a product in the same condition as new, or if you are concerned about minor details, please refrain from purchasing. There may be other stains or scratches that are not shown in the photos. Please purchase only if you understand that this is a used item. It will be shipped folded to some extent. Please understand. Size: 30-45L
