Size: Approximately 12cm in diameter x 7cm in height Material: Ceramic clay (ash glaze) Features: The natural gradation from pale gray to brownish-red is beautiful, and the flow of the glaze and the variations caused by kiln changes create a unique texture in each piece. The rim (edge) has a slightly undulating shape, providing a sense of warmth and stability when held. The bottom is unglazed, allowing you to directly enjoy the texture of the clay.
