Ever since the Moscow Mule was concocted back in 1941, it’s been consumed from an attention-stealing copper mug—like this one. This 12 oz. version is crafted from 100% pure copper and is perfect for your summer drinks—Moscow Mules or not. Since copper is a highly conductive metal, the mug will keep your cold beverage cold even on a hot day. Whether you’re pouring a mixture of vodka, ginger beer, and lime juice for your classic Moscow Mule, or you’re enjoying something else entirely, it’s sharp-looking piece of barware we recommend.
