No one knows exactly how the trend started, but over time, the Moscow mule—vodka, ginger beer, and a splash of lime—has become synonymous with its famous metallic cup. The Moscow Mule Time version of this iconic vessel includes all the necessities to keep drinks cold: a copper-plated stainless-steel mug with a solid brass handle. The company also keeps it personal with custom initial or monogram engraving. Elegant script in one of 11 distinct styles unfurls across the mug's façade, denoting the cup's true and rightful owner. Despite its name, the Moscow Mule Time mug is equally suited to keeping other drinks frosty, too.
