Tomokazu Noguchi Delicate beauty like a kaleidoscope! These rock glasses were designed and cut by traditional craftsman Mr. Hideaki Shinozaki. The interplay of transparency and color created by leaving a thin layer of color in between the cuts with his outstanding technique is truly kaleidoscopic. The contrast of the layered colors is clear, so this product can be used not only for drinking sake as a rocks glass, but also as a decorative piece. We hope you will enjoy its delicate beauty.
