This is one pleated cup by Akio Nunaga. It's like a large sake cup? Or a small bowl. I bought it a while ago at a department store in Tokyo. I've had it on display in a cupboard, so I haven't used it. Therefore, there are no noticeable scratches or chips. I'd like to pass it on to someone who will use it, as I don't have the opportunity to. Height: 52mm Outer diameter of the mouth: 73mm Thank you very much.
