The Le Creuset Wine Pump preserves wine by removing air from inside an opened bottle, then tightly sealing it using a durable stopper. By simply placing a stopper in the bottle and pumping several times, the wine is sealed and ready for storage. Includes three universal sized stoppers, extra stoppers are available to purchase. Insert stopper firmly into bottle, locate wine pump on top and pump until the air is removed. Clean with a damp cloth or warm soapy water.
