We have added a wonderful new item to our popular copper items. This copper tumbler is finished by taking into account temperature and humidity, and the time for coloring is calculated by the craftsman's years of experience. The finished pattern differs slightly from one to another, creating a unique and sophisticated tumbler.

This copper tumbler is made in TSUBAME City, NIIGATA Prefecture one of the world's leading metalworking towns.

The beautiful pattern on the surface is called TSUCHIME, means hammered pattern and was originally done by hand with hammer by craftsmen. Copperware made in this way became a true craft, not only functional but also beautiful to look at. The patterns on the surface are elegant, and the color changes as it is used, making it unique and one-of-a-kind. This traditional technique was reproduced by craftsmen using molds so that the copperware can be processed by modern machines. What used to take a tremendous amount of time, tens of thousands of hammering, can now be crafted in an affordable amount of time. The colors are applied using the traditional craft of hammered copperware coloring technique, in which the pieces are dipped in a coloring solution. AOKABUSE SHIAGE (it means “blue-colored finish” in Japanese) is a unique finishing method that is the result of many years of research by skilled craftsmen in the traditional technique of coloring.

This slightly smaller tumbler has a rounded shape. It fits comfortably in the hand when held. The unique texture and coldness of the copper will be felt on the lips, making cold tea taste even better.

Copper is oxidized when it is touched or held in the hands, and as a result, the tint and texture changes day by day. Please enjoy the change of color, a feature of the natural copper itself.

Copperware develops a rich luster as it is used, and since it is not breakable, it can be used for a long time. It is a lifelong product that can be used from generation to generation. It also makes an ideal gift.

(Please note that the coloring process is done by hand, so the hue and pattern may vary from piece to piece.)
