Thank you for viewing. I am clearing out a tea room. This item has been stored in the tea room unused. Zen Sasaki, a regular member of the Japan Kogei Association, Fukui Prefecture. Length: Approximately 14.5 cm Inner diameter of the mouth: 4 cm, 3.5 cm There may be some errors due to amateur measurements. The beautiful color and shape are wonderful, with a silver-like appearance and a dark navy blue or black hue. It was quite expensive when purchased. The owner had hoped to use it someday, but never had the opportunity, so I have decided to put it up for sale. Please examine the photos and understand before purchasing. Thank you.
