Traditional craft, a set of teacups from Kihachi Kobo. Negoro 4.5 sun, the surface has Negoro's random carving. I believe my grandparents purchased these a long time ago, and they have been stored at home for a long time. They are clean with no scratches, but I don't know if they have been used. This product is black, but I am also selling red teacups, which appear to be a different color (photos 11 and 12). Please check my account. If you purchase them together, I will discount the shipping cost.
