Size: Diameter: Approximately 12.5cm Height: Approximately 8cm The potter's mark is faint, but on the back, it likely says "Eiko," and I believe it is a tea bowl by Eiko Miyaji. Since I don't have detailed information, please make your judgment from the images. There is also a paper box that the tea bowl came in, but it is in poor condition, so I plan to dispose of it. The condition of the tea bowl appears relatively good, but there may be some stains and scratches due to aging. Please check the images. Please purchase with the understanding that this is a long-term storage item. Tea ceremony utensils
