Arita-yaki (Arita porcelain) - Nishiyama Diameter: Approximately 15.5cm x 17cm Height: Approximately 5cm I think it's easy to use because of its perfect size and height. I am selling it because I bought new tableware. It has no signs of use, and I personally think it's a relatively clean item. Since there is no original box, I will pack it carefully. Please understand that this is personal storage and measurements are approximate.
