This is a wooden acupressure roller from the Sanrio Hello Kitty health goods series. You can roll it with your feet or use it by hand to stimulate pressure points. I opened it, but I stored it in a dark place without using it much. It's made of wood, so I don't think there are any particular stains or damage. Please forgive any oversights as it is an old item. It's an item from about 25 years ago. The retro cherry-themed Kitty is very cute, so it's recommended for those who are looking for it. Please understand that this is an old item. We do not accept claims or returns after purchase, so please purchase after you are satisfied.
