This is a tea bowl for the tea ceremony. There is no box. There is 大◯ (Dai-maru) written on the bottom (see photo 5). Perhaps it's the name of the kiln. I'm sorry, but I can't read it. The diameter of the mouth is approximately 11.3 cm. The height is 6 cm. It has been stored at home for a long time. Please understand and acknowledge this.
