This item was passed down from a relative, so I don't have all the details. I am selling it to organize my belongings. Diameter is approximately 13.5cm, height is approximately 7cm. Comes with a box and cloth. There are instructions, etc., that appear to be from the time of purchase. There are markings, likely in pencil, on the instructions and box. According to the instructions and markings, it appears to be a work by Shigetoshi Nakazato of Sangen Kiln, purchased in 1984. While I don't see any cracks, I am an amateur, so please examine the photos to assess the condition before purchasing.
