Self-cooling ceramic mug (set of 2)

Summer, sun, cool drinks: The self-cooling ceramic mug from the Viessmann Selection ensures a good mood at a barbecue, in the park or at the beach, because no matter how hot the temperatures are your drink will stay cooled! A cooler or ice is not necessary for this: The material develops its cooling effect as soon as the cup is immersed in cold water or kept under the running tap for at least one minute. The open pores of the ceramic absorb the water, after which it can evaporate. The resulting evaporative cooling ensures a constant cooling effect and keeps the cups contents approx. 40% below the outside temperature. It`s quite certain, that the self-cooling ceramic mug will become the beloved companion throughout the summer!
