Hello. Thank you for looking. This is a brown and white backpack. It has an inner pocket and the shoulder straps are adjustable in 4 stages. A 500ml plastic bottle can fit both vertically and horizontally. It has a lot of storage capacity. It has only been used twice. I think the material is faux leather. There is a very small stain and some loose threads. (See photo 5) There is a faint yellowing on the bottom of the back. I don't think it will bother you when you use it. (See photo 6) I will ship it within 2 days. If you have any questions, please feel free to comment.
