The optional lid for the Can Coolers turns your cooler into a 12oz Tumbler!
To use the accompanying lid please unscrew the ring off the top, take the can or bottle out of the cooler if it is inside, and pour the drink into the cooler. Put the lid on top of your poured beverage and voila!
Please see below for an example of how to take the ring on top off!
