The Fizz keepers (pack of 4) enable the user to keep fizzy drinks fresh.
Simply remove the standard cap (will fit all standard plastic carbonated drink bottles) and replace with the fizz keeper.
This allows the user to pour the drink at will but when ready to close simply press the top part back on the bottle and squeeze the bubble on the top to put back the pressure in the drink.
This will keep even a big 2 litre drink fizzy right to the end.
Ideal for BBQ`s and picnics.
