This item was passed down from a relative, so I don't have any detailed information about it. I am selling it to organize my belongings. Diameter is approximately 10.5cm, height is approximately 7.5cm. It appears to be a tea ceremony utensil. It has engravings of a hell scene and a tornado. While I don't see any cracks or major scratches, I am an amateur, so please examine the photos to assess the condition before purchasing.
