Our best-selling sparkling wine stopper for over ten years! Simply push the steel stopper onto an opened bottle of champagne until 'clicked' close. The 12 separate grips underneath will lock onto the edge of the bottle and hold tight even under pressure. The bubbles will keep fresh inside for up to a week and you can even lay the bottle on its side without concern of leaking. To release simply press button on top of sealer. Fits most regular bottles of bubbly.
