Thank you for viewing. This is a tea bowl for the tea ceremony. I believe the mark on the bottom says "清" (Kiyo/Sei). It shows signs of use, but there are no cracks or chips. It comes in a paper box. The box is old. Size: Diameter...approx. 11.5cm, Height...approx. 7.5cm Please understand that this item has been stored for a long time before purchasing.
