Pure copper cup

Made in Tsubame City, Niigata Prefecture, a world-class metalworking production area. Copper is said to be the first metal used by humankind. It is a very excellent material because it has high corrosion resistance, has antibacterial properties, and conducts heat and electricity more easily than other metals. Despite its high price due to these characteristics, it is widely used in construction, automobile parts, marine paints, and electrical appliances. The base material is “pure copper,” which boasts a purity of 99.95% or higher. It is also a fascinating material that you will feel attached to, as it changes its color through oxidation and aging and transforms into a unique color and luster. A circular copper plate is slowly stretched over time to its present shape, scraped repeatedly in every detail, and then carefully polished. The pattern engraved on the bottom is called “uchide no kozuchi,” one of the treasures that appears in many Japanese tales since ancient times. It is also famous for being held by Daikokuten, one of the Seven Lucky Gods, and is an extremely auspicious object as it is said to bring forth various things and wishes when tapped out. It serves as a standard cup, sized for ease of use, adding color to the dining table for any occasion. 【Production】 Japan　Tsubame City, Niigata 【Size】 Cup：φ90×H81mm　capacity：350ml Coaster：W80×D80mm Paper box：W100×D100×H100mm weight：175ｇ 【Material】 Tumbler：Pure copper Coaster：Linen 【Spec】 Tumbler inside：Plating processing　outside：Clear painting
