This item was purchased from Ogiakei Kiln, a producer of Koishiwara-yaki pottery. I am selling it now because I have no opportunity to use it. There are two plates. Diameter: Approximately 19cm, Depth: Approximately 3cm I didn't notice it when I bought it, but the first plate has a crack on the inside. The original price tag is still attached, but I will offer a slight discount.
