A collaboration with Kamiyama Kobo, a pottery studio located in Kamiyama-cho, Myozai-gun, Tokushima (Shikoku). Made from a combination of three different varieties of clay, the tumblers feel gentle in the hand and are colored in a tasteful white. The addition of sand polished in the pristine Akuigawa River creates a naturally complex expression. *Each piece is made by hand and will have a slightly different color grading, pattern and shape.
