The Moscow Mule cocktail (vodka, ginger beer, and lime) was first created in 1947 and has always been best enjoyed in a frosty copper mug. This updated version of the classic mug is handcrafted from hygienic, easy-clean stainless steel with a copper-plated exterior and an easy-grip handle. The mug combines old-world charm and new materials to enhance your Moscow Mule experience. To clean, wash with warm, soapy water and dry with a soft cloth. Not microwave safe. Drink responsibly, of course.
