Please be sure to read the self-introduction! ^ - ^ Black Outside: synthetic leather, Inside: 100% polyester See image 12 for the size ☆ New, unused I bought it but haven't had a chance to use it, so I'm selling it. I haven't taken it outside once. I only adjusted the straps. Unused. There is a small white stain as shown in image 10, but I don't think it's noticeable. I would be happy if someone could use it ^ - ^ This backpack uses a material with a cracked, matte texture that enhances femininity. It has a silver matte finish for a touch of style, and both the pocket and hood have magnetic locks for convenient opening and closing. The straps are adjustable.
