ZeroPak Wine Stopper
Zeropak wne stopper or wine keeper
This is compatable with the ZeroPak Mini vac VS6620.
Push it into the top of any wine bottle (or similar) then use the hose that is supplied with the minivac, connect it to the mini vac then to the wine stopper and it will vacuum the air out so that the half bottle of wine will stay fresh 5 times longer.
You can also use it in many other bottles of similar size,
