This indigo blue guinomi sake cup, crafted by Seigado, boasts a rounded shape that fits comfortably in the hand and offers a smooth rim. 

This hammered copper sake cup radiates a gem-like sparkle, ideally designed for evenings enjoying sake. When paired with a katakuchi sake carafe, it elevates your table setting, bringing an element of refined sophistication.

A sheet of copper is carefully crafted using the traditional hammering technique known as tsuiki, to shape this sake cup into a seamless piece. Tsuiki is a metal crafting technique that involves hammering and embossing various metal plates, such as gold, silver, copper, and tin. The hammering marks are left as beautiful patterns on the finished products.

Copper's high thermal conductivity enhances the chill of cold sake, while the tin coating inside softens its flavor. The copper also deepens in color with use, adding enjoyment over time.

Seigado has perfected the process of achieving a unique indigo blue color. This deep, elegant blue is produced by inducing patina through immersion in a solution. Crafted with delicate expertise, these deep shades elevate the experience of drinking sake at home.

Seigado, situated at the base of Mt. Yahiko in Niigata Prefecture where high-quality copper was discovered 300 years ago, specializes in tsuiki. The Seigado workshop crafts items featuring a unique luster and durability achieved through repeated forging.

Note: The interior is tin-coated and not suitable for hot sake. Use this item for cold or room temperature sake. After use, wash with a soft sponge and dry thoroughly.
