The WAF patented Stopper seals by using the Sparkling Wine's CO2 to expand its internal patented valve. Designed for professional use, in our experience it can preserve your Parkside bubbles like new for over a week!
Tried and tested - this is the stopper we use in our cellar door.
Product manufactured by WAF Brevetti and made in Italy .... and with a Parkside logo.
(Price quoted is for a single stopper)
