A silicone stopper for sparkling wine and champagne bottles. The stopper preserves the bubbles in an opened bottle. The shelf life is a few days depending on how much wine and bubbles are left. Thanks to the patented design and the stickiness characteristic of silicone, effervescence is preserved in an opened bottle. Press the stopper all the way down so as to make it stick properly to the bottle. Incl. two stoppers.
