The Fresh & Save wine sealer is designed to work with the vacuum pump to keep open bottles of wine fresh for longer. The sealer slows down the oxidation process, preserving the aromas of the wine so that it tastes better even days after being uncorked. Dock the vacuum pump onto the wine sealer and with the push of a button, it extracts the air more the bottle is a few seconds. When a sufficient vacuum has been obtained, it stops automatically.
