The Frustum tea set was designed for a modern lifestyle and with the idea of continuing Japanese tea culture. Inspired by the shape of traditional iron kettles, once common in the Tōhoku region, the teapot showcases typical design features such as a conical bottom and a slightly offset edge. The conical tea cup rests comfortably in the hand, while its narrow opening bundles the fragrance. The earthenware teapot and tea cups are available in white and black.
