This is a flat rice bowl from the Ryoshu Kiln of Arita-yaki, featuring an ancient circular pattern. Size: 13 cm diameter x 5 cm height As it's a flat rice bowl, it's slightly larger than a regular rice bowl and can be used for rice, simmered dishes, and more. I purchased this some time ago and it has been stored at home unused. Please make your purchase based on the photos provided. During the listing process, I noticed that one bowl has a small air bubble trapped in the glaze. Please also check the photos for this. Similar products are currently sold on Rakuten and other sites, but since this item has been stored at home and does not have a box, I am offering it at a lower price.
