Thank you for viewing! (*^^*) This is a silicone multi-band from MUJI. I recently purchased it at the store and opened it. I tried using one black band, but I don't think I'll use them much, so I'm offering the remaining 11 bands to someone who needs them or would like to try them out. Please note that the outer bag has some wrinkles. Since it has been opened once, I would appreciate it if you could understand. Thank you very much.
