【Product Details】 • Brand: Glint Copper • Material: Pure Copper (100% Pure Copper) • Contents: Set of 5 cups • Size: Height approx. 10cm, Mouth diameter approx. 6cm, Base 4cm • Condition: Unused (with plastic wrapping) • Included: Wooden box 【Condition】 This is a new, unused item that has been stored for a long time. Although unused, there are areas with black discoloration as shown in photos 7 and 8. The inside of all the cups is clean. Personally, I think the included wooden box is also valuable. It would be stylish to use it as a container for screwdrivers or small tools. 《Main Features of Pure Copper Cups》 Excellent Cooling Power & Refreshing Feel When you pour a cold drink, the cup itself cools down immediately, and the coldness lasts longer, making it ideal for beer, highballs, and iced coffee. Antibacterial & Sterilizing Effect Due to the action of copper ions, it has a high antibacterial and sterilizing effect, making it hygienic (also used for flower vases). Aging The surface changes color over time as it is used, developing a more subdued color and making you feel attached to it. Thank you for viewing.
