This is a waterproof smartphone case from MUJI. Large size: MJ-WPC2 Thank you for viewing. Purchased new in April 2023 and used a few times, then stored. There are no noticeable stains or scratches. I have confirmed the waterproof function, but I cannot be held responsible after the transaction. Please understand this before purchasing. Please refrain from purchasing if you are concerned about minor details due to home storage.
