I received Akaiger Collections Barrel Hammered Moscow Mule Mug in return for my unbiased review. This is a very nice mug. It's made of 100% solid copper. Copper has very high thermal conductivity which quickly takes on the ICY temperature of a drink. The rim of your mug instantly chills which offers a frozen sensation to lips. This mug will keep drinks super cold. It's a sturdy and durable cup. It holds 16 oz of liquid. My husband loves this cup. He can pour his drinks--even beer- in this cup and it stays cold. There's no funny taste. The handle is big enough to get a good grip on the mug. It's easy to clean but not dishwasher safe. Overall, this is a great way to have a cold drink. My hubby can't wait to have his mug on hand for game-time. Highly recommend. You can find out more about Akaiger Collections Barrel Hammered Moscow Mule Mug @ http://www.amazon.com/dp/B013JH0R58.
