Effortlessly preserve the taste of your open bottle of wine with the Wine Preserver from Rabbit. Place 1 of the push-button stoppers in the bottle and gently pump out the air with the vacuum pump. This prevents the wine from oxidizing, preserving your wine and allowing you to enjoy it another day! Set includes 1 pump and 2 stoppers. The wine stoppers fit any size wine bottle and the pump handle is ergonomically designed for easy operation. The stainless steel body and accents bring tabletop appeal to wine preservation. The button on the top of each stopper relieves the vacuum pressure to re-open the bottle. Stoppers are dishwasher-safe for easy cleaning.
