This is a matcha tea bowl. It has been stored in its box for a long time. It has a square stamp with the inscription "[清]" (Kiyoshi/Purity). Size: Diameter: Approximately 12 cm Height: Approximately 7 cm Although it is unused, it has been stored for a long time, so I will consider it as "like new." I would be happy if someone could use it. The original box is stained due to aging, but I will use it for shipping and place it in a slightly larger box that I have on hand. Thank you for your understanding.
