Thank you for your interest. This is a celadon cup from Arita ware. I don't remember exactly, but I believe it was given to me by a salesperson from a department store. It has a lovely color, supervised by the Living National Treasure, Inoue Manji. The base has a diameter of 6 cm. The drinking surface has a diameter of 9 cm. It is 11 cm tall. The outer box is 9 x 9.5 x 11.5 cm. Please feel free to comment if you have any questions. Please see the photos for the condition of the box. It has been stored in the box and is unused, so the cup is clean. 205
