These are plates by Tomoyuki Touyama of the Okinawa traditional pottery, Yachimun, Kobo Mushinone (2 plates). I am selling these because I have too many plates. I forgot when I purchased them, but I used them for a little while. Please consider purchasing if you don't mind. There are no smokers in my family, but I have a cat. Please refrain from purchasing if you are concerned. Size: Diameter: Approximately 22cm Height: Approximately 4.5cm Material: Ceramic/Pottery Brand: Yachimun Shape: Round plate
