I don't know when it was purchased. No box. Unused. When laid flat, it's about 20cm, but because of the fur, it might feel a bit smaller. Based on my measurement, I think the size is around 17-18cm. * We do not ship to Okinawa or areas with relay charges. * For Hokkaido and Kyushu regions, shipping is an additional 500 yen, so please contact us in the comments.
