【Product Details】 This is a pure copper tumbler from Shinko Kinzoku (Shinko Do), a long-established manufacturer in Tsubame City, Niigata Prefecture. The beautiful hand-hammered "tsuchime" (hammered pattern) by artisans, combined with copper's excellent thermal conductivity, chills the vessel the moment you pour a cold drink, keeping it at the perfect temperature for a long time. The surface has a "tin/black plating" finish, giving it a calm and luxurious design. Enjoy cold drinks such as beer, highballs, and iced coffee at their best. • Brand: Shinko Do (Shinko Kinzoku Co., Ltd.) • Model Number: BR-202SB • Material: Body/Pure Copper (Inner surface: tin-plated, Outer surface: black plating/baked coating) • Capacity: 350ml • Country of Manufacture: Japan (Tsubame-Sanjo) 【Condition】 • New and unused.
