This bottle top for cans can be used for almost all 12 and 16 oz. cans; sodas, beers and energy drinks. The Snap Capp is easy to use, simply open your drink, snap it on and drink. It is air tight so you won’t have any spillage and the screw top lid will keep your fizz in and the bugs out! When you’re finished, pop it off, rinse it and use it again.
