ToTT Set of 2 Vacuum Wine Pump Stopper ToTT Vacuum Wine Pump and 2 Stopper Set is a vacuum pump that extracts the air from an opened wine bottle and re-seals it using a rubber stopper. The airtight vacuum inhibits the oxidation process that is responsible for the deterioration of wine. The vacuum is created by placing a stopper into the neck of the opened bottle and pumping it until resistance is detectable. They are used together to remove air from your wine bottle to keep wine tasting new for up to a week!
