Sumikko Gurashi Shirokuma Room Slippers Approximately 21cm Made of fluffy, soft fabric, they fit the foot well and seem wearable from around 18cm. I bought these for my child, but they weren't used much. Please understand that they have been stored at home. Because of the soft material, they only appear wrinkled in the photos, but they are fluffy and soft, and seem comfortable to wear. They still seem wearable, so if anyone would like to use them, please do.
