Left side: Diameter approximately 31cm Right side: Diameter approximately 31cm This item was in my husband's family's storage room and doesn't seem to have been used much. I believe it's from the Showa era, but I don't know the details. I also don't know what kind of pottery it is. I would be happy to pass it on to someone who can make good use of it. I will pack it carefully and ship it. Thank you. I'm estimating 850 yen for shipping, so I can't offer a discount. Material: Ceramic/Pottery Shape: Round plate Item Type: Large plate
