Best Soda Can Lids Silicone Wine Stoppers – Replace a cork – Airtight seal on Wine Bottles – Reusable Beer Bottle Cover – Wine Bottle Stopper – Wine Saver – Wine Gifts – Easy to clean! (2 Pack, Grey)

Perfect for saving pop or wine. Seal is excellent and easy to take on and off. Bought extras to give to friends. We don't use any other stopper now.

These work very well. Snug but not too snug.

These stoppers are great. Even caps off champagne bottles.

These work surprisingly well. They stretch to fit tightly on bottles -- and work on glass soda bottles or beer bottles, too. I haven't used them extensively yet, but they do seem to be able to keep the fizz in an opened soda bottle. So, that is a "plus". They appear to be leak proof so long as they are fitting tightly on the bottle. Obviously, not all bottles have the same shape at the top, so it is possible that a particular type bottle will not be leak proof with one of these as a stopper. But, mostly, they seem to work well. A big advantage of these is that they do not make your bottles "taller" -- meaning that storing them in your refrigerator (or wherever) is made easier by not requiring an "extra-tall" space to stand the bottle in.

Caps work as advertised, sometimes if there is an extra thick top on a bottle the cap has to stretch a bit but it does, might not go down as far as normal but it keeps the wine in even if the bottle is turned sideways.
