I am selling this item to clear out my grandmother's house. She frequently visited the kiln and purchased pieces, so I believe this is a work by Koyo Kumagai. I believe it was purchased between 1980 and 1995. There is no box. Condition: Unknown how many times it was used. Please judge from the photos. I believe it is in very good condition with no scratches or chips. Size: Diameter 13.8 cm, Height 10 cm Weight: 534g I will also be listing other tea ceremony items and pottery from Kitakyushu, so please take a look at my other items if you are interested. I will not be able to lower the price for about six months after listing.
