This is a small sacoche, measuring 16cm in height, 13cm in width, and 19cm in thickness (at the widest part at the top). It's a good size for carrying a smartphone, a small wallet, and keys. I've categorized it as a men's sacoche, but it has a simple design that can be used by anyone. I bought it in a store a few years ago, but I usually use a slightly larger sacoche, so I haven't used this one very often. It's similar in shape to the following product: https://www.muji.com/jp/ja/store/cmdty/detail/4550584950629 Material: Nylon Color: Beige Condition: No stains or tears
