The cooler is filled with a special transparent cooling liquid. The use is remarkably simple. Just put the whole bottle-cooler into the freezer for a couple of hours before use. The cooling liquid in the cooler will then freeze and keep the temperature for a longer time. Water, wine, sparkling wine and champagne will thus stay cool and fresh for up to 3 hours.

Real ice-crystals appear on the outside of the cooler during melting (real-frost-effect***)... an optical highlight, which should not be missed on any table!
