These work wonders, as I travel thru different elevations quite frequently. No more spills in my bags and easy to clean off the inside. Must have! Even my mom desperately wants some now😆

These are rubber bottle seals to keep wine fresh. I think they do an adequate job. If left for a day or two u can tell the air left in the bottle has caused the rubber to balloon a little, so obviously it's not allowing air to penetrate in OR out. I think it worked from my usage experience. I prefer using an air release cork with this over it though, its like dbl the blockage, and wine seems to last a few days or more without an issue. I pump out the air with the pump and cork set, and put this over that. Of course, they're easy to store and with good durability, stretching over and over, no breaks or tears. I think its probly even a safe way to prevent spills if it were to tip over. You just gotta squeeze the air out that gets caught under, but easy enough to do. Handy contraption.

Even though we have wine stoppers in the house, more than a few of them don't let us put bottles back on the shelf in the fridge. These are easy to put on the bottle and are easy to wash. Because of the material, they do collect and hair or whatever debris is around, (dropped one on the floor, which I thought was clean) but rinse off easily.

I like a glass of wine in the evening and rarely drink more than that, thus have a partial bottle sitting around quite often. Corks are usually ugly on one end and hard to push back into the bottle. But the LeakLocks solve this problem by becoming a slide on sleeve over the neck of the bottle in place of the cork. Made of stretchy silicon, they fit tightly. Pulled all the way on, they have a little "give" and will bubble at the mouth if the wine expels any gas without the gas escaping (meaning they seal well). When done, I pop them into the dishwasher over a prong so that they drain naturally. A great way to save partial bottle of wine! Like a prophylactic for a wine bottle, keeping you safe for another time!

I've used silicone bottle sealers before for toiletries, but I didn't realize these would be a stretchy as those - the look of the textured material threw me off! These bottle sealers are SUPER stretchy (my whole hand can fit inside! haha) which is awesome because that makes they really easy to stretch over the top of any bottle. So far they are leakproof and really perfect for capping my wine. I've bought wine bottle caps in the past made of many different materials, and with each of them they eventually break (yes I'm a big wine drinker). I really can't see how these would break, so I'm pretty happy with them. Cute colors too, very subtle and it's not like you'd want bright purple on top of your wine bottle. The textured look makes them look more expensive/more elevated than just silicone.

I love everything about these! They are light, stretchy, easy to use and keep the bottle fully secure from leaks - need I say more!!! I am reducing my review from 5 stars to 4 - these initially worked fantastic but did become stretchy and looser after 4-5 uses and could easily be pulled off. However, considering the price and that this is for 4 stoppers I would note that these are disposable once they stretch out.
