ZeroPak Wine Stopper
ZeroPak Wine Stopper or wine keeper
The zeropak wine stopper is compatable with the ZeroPak Mini Pro Vac.
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 the zeropak wine stopper in many other bottles of similar size,
