This is a teacup by the artist Yasuhiro Kotani. It has never been used since purchase, but has been stored at home. There are pinholes, black spots, and cracks (called "nyu" in Japanese) from the beginning. The soft white glaze drips are also lovely, though difficult to convey in the photos. I think it could also be used as a small bowl. Please understand that this is a used item. SIZE: Outer diameter approx. 9.7cm, height approx. 7.4cm
