Simple and functional gray backpack from NORDACE. I used it for about 3 months when going out on weekends and holidays. The vinyl in the inner pocket is whitish, but otherwise, I don't think there are any noticeable stains. If you have any concerns, please comment! I will add photos! - Brand: NORDACE - Material: Nylon - Design: Simple and functional backpack - Straps: Adjustable shoulder straps - Pockets: Side pockets on the outside Thank you for viewing.
