Pure Copper Cup Set (2), with Coasters, in Paulownia Box, Matte & Brown

Copper is said to be the first metal used by humans.
It is an excellent material that is highly corrosion-resistant, has antibacterial properties, and conducts heat and electricity better than other metals.
Although its characteristics make it expensive, it is widely used in buildings, automobile parts, ship paints, electrical appliances, and more.

The base material is "pure copper" that boasts a purity of over 99.95%.
It is an attractive material that changes color through oxidation and aging, developing a unique luster and color that will make you grow to love it.

A circular copper plate is slowly stretched over time to give it its current shape, then every detail is repeatedly scraped and carefully polished.

The pattern engraved on the bottom is called the "Uchide no Kozuchi" (Lucky Mallet), a treasure that has appeared in many fairy tales in Japan since ancient times.
It is also famous for being held by Daikokuten, one of the Seven Lucky Gods, and it is said that when it is struck, it will bring about various things and wishes, making it a very auspicious item.

The size is designed for ease of use, making this a standard cup that will add color to your dining table in any situation.

This set of two comes with a coaster and comes in a luxurious paulownia wood box, making it the perfect gift for wedding favors, friends or superiors, or as a thank you gift.
