The Magisso® Naturally Cooling Ceramic Carafe is perfect for everyday use and great for entertaining in style. To cool the carafe, simply soak it in cold water for 60 seconds. Remove from the water, towel off the carafe and fill with your favorite beverage. As the water evaporates, the ceramic carafe naturally cools your drink and keeps it cool for up to four hours. The longer the carafe sits in the open air, the cooler it becomes. The matte black exterior has a surface similar to a blackboard, so you can personalize your carafe with chalk drawings and writing. Holds one liter.
