Size: Approximately 8 cm in diameter, 7 cm in height Is it deadstock? It's in a condition with little sign of use. In the last photo, near the tip of the ballpoint pen, there is one very short hairline crack in the surface glaze. (It is not a crack that goes through to the back) This is not a corporate item often seen in the market. The sides are plain, and it's a pure sake-tasting cup. The kiln name is written on the inside of the foot on the back. The size is not a small giveaway item, it's a vessel that holds a generous 1 go (about 180ml), perfect for drinking sake from a glass. Drinking sake at home with a sake bottle and cups collected as a hobby is also good, but sometimes drinking directly from a 1-sho bottle into a glass is also nice.
