I purchased this at the Konohana Museum in Lake Kawaguchiko. It's a bookmark featuring Dayan the cat. I've used it a few times. I don't see any noticeable stains, but please understand that this is a used item inspected by an amateur and stored at home. - Museum Name: Konohana Museum - Character: Cat with wings - Design Style: Illustration - Size: Approximately 11 cm (height) x 4.5 cm (width) Thank you for looking.
