This is a stringing toy in the shape of cheese. I bought it as an educational toy. I forgot whether the tip of the stringing part was a mouse. I bought it about 8 years ago, but I haven't played with it very much. There are no noticeable stains. I would appreciate it if you could understand that this is a used item. Please refrain from purchasing if you are sensitive to used items. It will be shipped via Mercari Bin Yu-Packet Plus. Toy genre: Educational toys/learning toys
