Height: Approximately 118mm, Mouth width: 80mm Weight: Approximately 250 grams Original black tenmoku glaze and red crystal glaze, two-tone, fired at 1230°C Inspired by the shape of a shell, and the gesture of raising a fist in triumph when achieving something. The bumps are created by mixing coffee grounds into the clay before firing. I proposed this improvement with the small goal of contributing to the SDGs. Please enjoy the easy grip, light weight, and feeling of luxury.
