Showa Retro 70s Sanrio Hello Kitty Mirror Originally, it was a towel hanger with a Hello Kitty mirror from Sanrio in the 70s, but the hook part has come off. It can only be used as a mirror, but it is quite old-fashioned. The adhesive part on the back has deteriorated over time. Size (maximum): 13.5 x 12.8 cm.
