Capabubbles® is a reusable silicone cap that reseals a bottle of sparkling wine once it is opened. An adaptation of the original CapaBunga®, it transforms a bottle of sparkling wine into a screw cap bottle. The cap has a threaded insert that once unscrewed from the base clips under the flange of the sparkling wine bottle, the cap is then twisted down on top of this piece preserving the bubbles in your champagne or sparkling wine for up to one week. these are shipped in tubes. Great gift for a prosecco or champagne lover.
