Copper Sierra Cup

Copper cups with a rich texture created by spinning

The weight feels comfortable in the hand and the handle is stable and easy to grip.
The more you use it, the more the unique texture of copper will become.
The Copper Sierra Cup fits comfortably in the palm of your hand and can be enjoyed at your leisure.

Copper has excellent thermal conductivity, so when you put it on the fire, the heat spreads all over the pot at once, allowing you to boil water or cook food quickly.
The 500 has a base diameter of 9.9 cm, making it stable even when placed on a trivet. The large handle fits comfortably in the hand with your index finger and is easy to grip even when wearing gloves. The handle is made of brass for added strength.
When camping, it can be used as a cooking utensil, ladle, cup, or dish substitute.
Copper develops a beautiful texture the more you use it, enhancing the atmosphere of your campsite.

How a single copper plate becomes a living tool

99.9% purity. Made in Japan with the finest craftsmanship.
A one-of-a-kind product that lets you enjoy the aging process.
The Copper Sierra Cup is manufactured in Nagaoka City and Tsubame City, Niigata Prefecture, a city of metal processing that spreads across the Echigo Plain.
These copper products are handmade one by one using the now rare technique of "spatula-drawing."
The craftsman stretches the metal while interacting with it, and the copper tightens and becomes stronger without being subjected to stress.
It is breathed new life into a tool that will last a lifetime and be passed down to the next generation.
We paid particular attention to the feel on the lips and the curl around the mouth.
