Tumbler 270ml Aging Blue Regular price: ¥36,300 Copper, the first metal used by humankind, has been used in various household items. This is an attempt to create a bottle that allows you to experience the origin of metalworking with this historical material. In searching for a new expression that is neither painting nor printing, we arrived at the copper coloring technique that has been passed down for over 400 years in Takaoka City, Toyama Prefecture. The verdigris pattern, created by this technique, which has been used in crafts such as vases, incense burners, and tea utensils as a craftsman's skill to give delicate warmth to inorganic metal, is applied to the surface. Because each one is colored by the hands of craftsmen, each one has depth and a unique expression. This is a new form of tradition created by the fusion of the skills of craftsmen from across the boundaries of materials and production areas. The standard 270ml size is perfect for a quick hydration or when you want to take a break, and it's easy to carry around. Series Introduction To an unknown expression that connects accumulated tradition with the present.
