This is a coaster from the collaboration between "The Night is Short, Walk On Girl" and the Bungu Cafe. The front side shows no noticeable stains. The back side has some minor stains. Please check the images and purchase with your understanding. I understand that some people may only want the girl with black hair and Hanuki-san, but I will only sell them as a set. Actually, the other two are extras. I will take measures to prevent water damage and folding, and ship via Rakuraku Mercari. Girl with black hair (Koi) Hanuki-san Pants General Li Bai
