Keep champagne fresh and bubbly with the Delvino Champagne Stopper - Pump. The pump action pumps oxygen into the bottles, helping it to taste fresher the next time you reach for a glass. Just place the pop stopper firmly on the bottle, clamp the sides down and pump the stopper to create pressure. To remove, simply lift the stopper to release the seal. Available in both a black and stainless steel finish.
