Ice block cans are perfect when you want cool and fresh soft drinks or other breweries in a can or bottle. The ice block cans fit around a can or bottle making sure the container is surrounded with an ice-cold cooling element. Just place the non-toxic cooling elements in the freezer overnight and you are good to go. And if you use them with one of the many different cool bags from Outwell you will even go in style. Each pack contains two 600ml reusable ice block cans.
