Love the Miller kangaroo sweatshirt ? Then you'll probably be a fan of Beer Savers  ($13 for set of six). These stretchy silicone bottle cap covers are designed to fit a standard glass beer bottle, keeping your brewski safe, not stale — and they can be reused after a rinse in the dishwasher. Much like beer bands , Beer Savers also help you identify which bottle's yours. My only thing is: do you ever not finish a bottle of beer? I don't!
