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 tastebuds since the 1940's. That famous blend of vodka, ginger beer, and lime juice can be enjoyed, especially so, with OUR set of 4 Hammered Moscow Mule Mugs. Featuring an attractive hammered finish to please the eye, each mug is also made of Solid Copper, which not only keeps your drink cool, but brings out the flavors of your mule recipe. These mugs are built to last with lacquered coating to prevent tarnishing, and nickel lining for easy maintenance. Our Hammered Moscow Mules are not intended for dish washer use. Doing so will cause product discoloration. Hand wash with warm soapy water, and dry thoroughly with a dry cloth. This product is not microwave safe. Look for the "ODI" stamp on the bottom of your mug to guarantee you’re drinking out of an ORIGINAL Old Dutch product.
