This is a Cinnamoroll muffler from Sanrio. I've used it a few times and stored it in a chest. I don't think there are any noticeable stains, but I might have missed something. *Please read the profile before purchasing.* Please understand that it's difficult to keep it in perfect condition as it's been stored at home by a private individual. If you wish to return it, please contact me via message without rating the item. Thank you for looking.
