A mug by Otaru ceramic artist Hiroshi Mitsuwa. This beautiful cup features a gradation inspired by the Sea of Shakotan. I bought it a few years ago but haven't been able to use it because I felt it was too precious, so I've kept it stored away. I'd like to pass it on to someone who will use it. I am also listing a plate from the same series. Diameter: 8.7cm Height: 8cm
