This is a DAKINE backpack. The color is dark gray x turquoise blue. The size is approximately 45cm in height, 31cm in width, and 14cm in depth. There is a zipper on the flap where you can put thin items like a commuter pass (see photo 6). Inside, there is a zippered pocket about 17 x 22cm (see photo 10). There is also a zipper on the right side of the back, which has a space to put thin items across the entire back (see photo 7). The back has cushioning, so it keeps its shape and is well-made. It has only been used once, and I think it's a beautiful item with no stains or dirt. However, please check the creases on the belt from storage (see photo 4). Please understand that this is a used item. Thank you.
