Size of the teacup: Diameter: Approximately 11.3cm Height: Approximately 8.7cm Weight: Approximately 385g It appears to have a matching box and cloth. Based on my research, it seems to be a work by Josuke Kato. The lid says "○An Sensei's calligraphy." Is the calligraphy on the teacup also by that person? I don't know the details, so please judge from the images. There don't seem to be any noticeable scratches on the teacup, but please check the images. The box appears to have a broken string, and there is dirt and wear due to aging. Please understand that this is a long-term storage item before purchasing. Tea ceremony utensils
