Each of your two Magisso® Naturally Cooling Ceramic Glasses will keep your water, wine or your favorite drinks colder longer—even in the hottest weather and without any ice cubes! Just soak the ceramic "glass" in cold water for a minute to initiate the evaporative cooling effect. As the water evaporates, the ceramic cools, keeping your glass approximately 40% cooler than the ambient temperature. For special occasions you can also write on the non-slip surface with normal chalk to be sure you don't lose your drink. Each holds 11 fluid ounces and is dishwasher safe.
