For the Moscow Mule connoisseur, a copper cup or mug is a must have. This gorgeous copper mug featuring a rustic woodland motif with a classic monogram makes a practical gift for your groomsman, best man or anyone who enjoys a popular drink. The most scientific benefit of using copper Moscow mule mugs is temperature. For centuries, the best drinkers have known that chilled drinks in copper cups offer an extra-cool sensation, due to the metal quickly taking on the icy temperature of the cocktail. Give these beautiful mules to a friend, bridal party member, or allow your guests to enjoy as you pass your favorite cocktail.
