To use the $12.98 Fizz Saver, “simply screw it on the top of your bottle, flip it over, place it on a flat surface and you’re good to go.” Though it may keep the soda carbonated for a few extra days, we still recommend finishing the bottle off in a timely manner to ensure freshness.
Fizz will last until the bottle is empty. Great for use at home, office, camping, entertaining and more. Plastic, 51/2 x 51/2 x 31/4.”
