Okay. I have a cat. There are no smokers. This is a handmade bookmark. The design paper is sandwiched between laminating film. A slightly stiff film is used. The sealing stamp may tear if pulled, or melt if left in a hot place. Please be careful. The corners are rounded, but there may be some unevenness or snagging, so I will sand them before shipping.
