Repour Wine Saver - Wine Preserver - Wine Stoppers - Wine Bottle Stopper - Absorbs Harmful Oxygen from your Wine, Simply and Effectively - Black 10 Pack

They work. I've drank wine that was over a week old. And it was as good as when I opened it. Amazing. At first I thought..... "So I threw these away after afew uses? " What a waste. But no I just pop them on another bottle . Still works ! I'll buy them again when needed.

We switched from vacuum-type wine bottle sealers when a special bottle was ruined within a week. We have had great luck with Repour, as well as Encork. No pressure to finish a bottle or sacrifice taste; consistently works well. We are repeat customers.

Allows to keep wine for at least three weeks (refrigerated with not intermediate opening). Price worth it if you drink quality wine.

Easy to use. Very quick delivery. Good price for 10. Downside: it’s a one use product and not easily recyclable.

Not sure if you can wash them before use. I threw them away. Glue on stopper
