The Polar Camel Wine Chiller is constructed with double-wall vacuum insulated stainless steel that will keep your wine bottle the perfect temperature for hours. For best results, pre-chill your wine bottle or the wine chiller in the fridge until you��re ready to use. Fitting most wine bottles, put your bottle into the chiller and screw on the lid to enjoy chilled wine anywhere. The non-slip silicone base allows for quiet and secure placement.
