Set of 5 copper "barrel-shaped" mugs. Made of copper, which is said to have high cold retention properties. Due to its very high thermal conductivity, the coldness of the drink is instantly transferred to the entire cup, keeping it chilled for a long time. Condensation also occurs easily, creating a cool appearance. The handles are made of brass. The bottom has some thickness and weight. *After purchase, I used them a few times and stored them carefully, but there are changes due to aging due to the nature of copper. 【Size】 Diameter: Approximately 6.7cm Height: Approximately 9.5cm *Regarding the unique changes of copper, it dissolves in acetic acid contained in vinegar, so it is said on the internet that you can restore the shine by gently polishing it with a mixture of vinegar and a small amount of salt. *Please understand that these are used items. #Copper #Mug #CopperMug #BeerMug #Outdoor #BarrelShaped #Beer #SetOf5 #Celebration #Party
