The wine stoppers are made of ABS & 100% Food Grade Silicone. The wine bottle stopper can help to keep the wine tasting fresh for up to 15 days in a simple way. Our upgrade vacuum wine stoppers have come with an in-built vacuum pump. You just insert the stopper into the bottle and expel air by pumping the rod up and down until you feel some resistance.
