This cup is one of my favorites I love my moscow Mule mug. This cup is perfect for serving Vodka,Ginger beer and lime juice cocktails. This is hand crafted solid copper. Not to mention I really love the way it looks as well. This is a very nice quality cup. The Moscow Mule Mug was born of a legendary 1941 meeting between smirnoffs American distributor and Jack Morgan of the infamous cock n Bull Tavern on sunset Boulevard, this is the cocktail that ignited the American craze for vodka. I thought I would share the back story, Which I think is pretty freaking cool. When you buy this mug on the back is a Moscow Mule Recipe. You also get a bonus of a download of special cocktail recipe booklet containing Moscow Mule and other awesome fun cocktail recipes. This awesome moscow mule mug is easy to clean you just hand wash it with warm water and liquid dish soap. Towel dry with a soft cloth never soak it in water. Never use this moscow mule mug for coffee or tea or other hot beverages. Do not use in the microwave or the dishwasher.This is a kick butt mug and you want to keep it that way.
