Air Pump Wine Stopper

Constructed of TPE, AP, & Acrylic\nVacuum seal pump that extracts air from an open bottle to allow the wine to taste fresh & last longer. The goal of this rather simple operation is twofold: to create a good seal to prevent air from entering the bottle and, more importantly, to reduce the oxygen remaining in the bottle, thereby slowing down the rate of oxidation of the wine.\n
