This is a Hagi-yaki teacup. Size: Diameter: Approximately 70mm Height: Approximately 80mm There is a mark on the bottom of the teacup, but I can't read it. It's also written on the box, but I can't understand it. If anyone knows, please let me know. It's unused, but it has been stored at home, so please refrain from purchasing if you are sensitive to this.
