The Duff Beer Frosty Mug keeps beverages icy cold without diluting them.

The Frosty Mug is made from plastic, and sealed inside the plastic is a liquid.

Simply put the frosty mug in the freezer until the liquid has frozen, and enjoy a cool refreshing beer each and every time. Homer would be proud!
