Thank you for viewing! This is a set of two copper beer tumblers from the long-established manufacturer, Shinkinzoku. They feature a beautiful hammered copper design, giving them a luxurious finish. Copper has excellent thermal conductivity. When you pour a cold drink, the entire cup chills, making your beer taste even better. 【Product Details】 ・Shinkinzoku ・Copper Beer Tumblers (COPPER100) ・Made in Japan ・Set of 2 ・Size: Approximately 8cm (top width) x 13.5cm (height) ・New, unused (only opened for photography) ・Instruction manual included ※Outer box not included ※Please refrain from purchasing if you are concerned about minor details due to home storage.
