Don't let your beer (or favorite non-alcoholic beverage for that matter) get all warm. Keep it cold with this Coozy style can holder. Just to make sure they work, we've tested these on various cans and bottles. I know for a fact that they fit Budweiser, Coors, Pabst and Miller cans perfectly as well as Corona and Fat Tire bottles. When the temperatures drop to below 32 degrees this amazing can holder also works in reverse to delay the freezing of your beverage and hand. Not compatible with Red Stripe, Lucky Lager or Olde English 800.
