Thank you for looking. This is a tea bowl for tea ceremony, in a biwa (loquat) color. I don't think it's Hagi ware. There is no accompanying box or anything else. It is in beautiful condition with no cracks or chips. The mark on the back, I believe it says "Ishi" (stone). It was a gift, so I don't have detailed information. Size: Diameter...approx. 13.0cm, Depth...approx. 6.0cm Please understand that this is a long-term storage item before purchasing. Thank you.
