Shinko Metal Pure Copper Play Cooking Sierra Cup, Medium, PL-1808

A must-have for camping and BBQ lovers! This one-of-a-kind item can be used for boiling, grilling, and simmering, and even when placed next to a stainless steel Sierra cup, it stands out as a unique and distinctive piece. It's a one-of-a-kind outdoor accessory, original to a copper products manufacturer. The copper Sierra cup's high thermal conductivity allows heat to be distributed evenly throughout the cup, allowing you to boil water in a short time. It also ensures perfect cooking even when using an unstable heat source like a campfire. The copper's unique color changes over time, developing a rich, mellow copper hue. Copper purifies water through a special effect known as "metallic oligomerization." This effect is called the "copper ion effect." The antibacterial and disinfecting properties of copper ions last almost permanently, preventing the growth of bacteria. *Please be careful not to burn yourself as the handle becomes hot.
