This Peugeot Replacement Wine Stoppers set has four stoppers designed for use with the French company's single-action wine pump and their double-function wine and champagne pump. This set of four wine stoppers serve as replacements for the couple already included in the wine pump set, which is sold separately.
These stoppers are the same size and shape. They fit tightly into any wine bottle and help preserve the leftover wine for the next few days. The grooves of a wine stopper have flaps all around the base to create an airtight seal. This protects the wine's color and flavors from losing their brightness. It also prevents wine spills and further fermentation of the bottle's contents.
