This special sake cup is hand-cast by skilled artisans in sand, which results in their unique textured finish and soft, lustrous glow. It is made of 100% solid tin, which has natural antibacterial properties and imparts no taste, allowing you to enjoy the sake flavor fully. Produced by a 100-year-old company in Takaoka City, the historical capital of Japanese metalworking. In 1916, the company began manufacturing traditional Buddhist ritual objects, tea sets, and vases made of brass and bronze. Today their expertise has expanded to design and create high quality metal objects for the modern home, specializing in sand casting production techniques.
