Thank you for viewing. This is a teacup made by Seizo Inoue, a gift received over 20 years ago. Detailed explanations of the Kin'gan rock are at the end of the photos, but it is written that it maximizes the natural flavors of tea, coffee, black tea, etc., making them mellow. It also states that it can be enjoyed with sake, whiskey, and shochu. When you hold it, there is a gentle indentation for your thumb to rest comfortably, and the color has a rustic, calm feel of the earth. We kindly ask for your purchase if you understand that this item has been stored at home for a long time. We will pack and ship it in the original box shown in the photos. We are sorry, but returns are not accepted. Size: Height: Approximately 9cm, Diameter: Approximately 7.7cm Ceramics Tableware Teacup Teacup
