I bought this a few years ago in Miyagi Prefecture (Sendai) because I liked the design, but I haven't used it at all because it's apparently not suitable for dishwashers, etc. I'm putting it up for sale since I won't be using it in the future. I believe it's the same item as the one on the following website. Since the manufacturer is the same, I'm sure it's correct. The patterns seem to vary slightly from piece to piece. https://tohokuru.jp/collections/miyagi/products/4-or04-02?variant=36529331667103 Made by Tohoku Standard Market x Miwada Kiln Made in Ishinomaki City, Miyagi Prefecture Size: φ100 x Height 80mm (including handle) Material: Ceramic Care Instructions: - Please note: Do not use in microwave ovens, ovens, or dishwashers.
