A fun way to serve vodka shooters. These Moscow Mule Copper Mug Shot Glasses are sure to be a hit at your next party. The Mini Moscow Mule Mugs look just like conventional Moscow Mule mugs with their copper exteriors and contoured brass handles, but at 2 ounces in size, they hold as much alcohol as a classic shot glass. Perfect for serving chilled vodka shots, these mini mugs are a stylish alternative to plain old glass shot glasses and can double as a decorative item when you’re not entertaining.
