This cool new Open - Close Bottle Capper is no mere bottle cap opener. It can also recap a bottle of beer or soda just as easily. Perfect for resealing a bottle that you want to finish later, preventing fizzy carbonation loss, or just keeping thirsty flying insect pests out during a backyard BBQ. If you're in need of a new bottle opener, then it might as well have a handy built-in recapper as well.
