Magisso Black Terra Cotta Self-Cooling Beer Tumbler

This literally cool new Magisso Black Terra Cotta Self-Cooling Beer Tumbler stays naturally cold for hours after being soaked in water for just 90 seconds to start the cooling effect - no trip to the freezer required. It holds a generous 19.2 fl oz of your favorite brew or brews since it self cools for hours and the black terra cotta material can be written on with chalk too if you find some clever reason to do so. Very unique and a great vessel for beer lovers.
