KLOUD City Pack of 5 Candy Colors Food Graded Durable Silicone Wine Beer Beverage Glass Bottle Caps Stoppers Sealer Cover

I could not get cork tops off of olive oil bottles. These solved my problem They keep the oil fresh yet easy to get too.

They work far, far better than advertised. When cost is factored in, it becomes a no contest with other preservation “systems”.

I love the way these work on my glass pop bottles. These wear pretty well, even with me tossing them in the dishwasher. I use themalot and probably replace them every two years or so. I consider this totally acceptable when set against all of the pop and other carbonated/non-carbonated beverages these have saved for me.

Poured half of a beer, then stoppered the rest with this stopper. After 3 days, most fizz/carbonation remained. Didn't expect this to be as effective as a good clamp style stopper for keeping fizz long term, but I was impressed that it did as well as it did. There are internal ridges which appear to match up with ridges on beer and wine bottles, which I assume creates a tighter seal. Screw cap beer bottles might give a different result.

I got these for bottles without screw tops. The only problem is, some carbonated beverages have so much fizz that it pops the top off. If there is not too much fizz, it works fine.
