What better way to serve the timeless Moscow Mule than in an Old Dutch Moscow Mule Mug. The Moscow Mule is a classic cocktail usually served in a copper mug that has been refreshing taste buds since the 1940's. That famous blend of vodka, ginger beer, and lime juice can be enjoyed, especially so, with our new 2ply Moscow Mule Mug. With a hammered copper exterior layer bonded to a 18/8 stainless steel interior, they’re stylish and durable. There’s no cheap copper-plating involved. This mug is double-walled with a full layer of copper and a full layer of stainless steel to make a superior Moscow Mule Mug.
