Before you guys think anything wrong, just hear me out on this. It's not what it looks like... honest! Best I can tell is it's like whiskey stones, but for beer. You put it in the freezer and put it in a bottle of beer to keep it cold when chillin' outside. It has a mouthpiece, so you don't need to remove it to enjoy. I'm a bit skeptical, but I'll give it a shot. (Seriously though... could they have made it a bit less... ya know.... :-P )
