These are MUJI's foldable polyester sorting cases. This is a set of three: one orange S-size pouch and two M-size pouches, for storing clothes, etc. None of them are mesh type, and each has one zipper. They are not compressible. They are thin, light, and pocketable, so they can be folded up small when not in use. There are no stains, but they are used items, so I would appreciate it if you could understand. Thank you.
