Pack contains 2 chillsners. The Chillsner contains a non-toxic thermal gel that once frozen will keep your beer cold up to 45 minutes. Made from food grade stainless steel the Chillsner will not impart any flavour on your beer. The stainless steel design allows for durability and easy cleaning. Flow through design means that the Chillsner does not need to be removed from the bottle for drinking.
