Are you shopping for the best double walled stainless steel mug? You are in the right place because we have it too in our collection. Our beer mugs are uniquely differently from standard glass or plastic beer mugs because they are stainless steel and copper plated. This means you can enjoy the cold temperature of your favorite bottle of Heineken or Corona without adding ice every now and then. We've even made them double walled so they will stay cold longer than your average glass beer mug.
