We've all done it! Opened a bottle of wine and felt obliged to drink the whole lot rather than let it spoil then in the morning - Wuhh!
Now there's no need. Push the stopper into the neck of the bottle, place the pump over it and pull the plunger up and down until you hear a 'click'. Then you know you reached a vacuum and theres no more air in there to spoil your wine.
Makes a great gift for a wine lover. Available in white or black.
