Now you can finally enjoy your beer the way it was intended to be enjoyed; perfectly chilled from the first sip to the last. The Chillsner uses Corkcicle's proprietary thermal gel technology and encases it in a special tube designed to fit securely into a standard size beer bottle, so you can chill your beers the same way you chill your vino. The Chillsner also boasts a new feature, a drink-through spout, which allows you to sip your perfectly chilled beer without having to remove the Chillsner. Ideal for picnics, tailgating, or a day spent fishing by the lake, this is the only in-bottle beer chiller that keeps your beer at the perfect temperature, from first sip to last. Just chill it in the freezer for at least two hours before use, and you'll be sipping that ice cold beer whenever the occasion calls for it. Set of 2.
