LEEFONE 18-Pack Silicone Rubber Bottle Caps: Reusable for Soft Drink, Wine, Beer and Soda Bottles - Kitchen Gadgets (6 Colors)

Doesn't pop off from the bottle tops

I can't believe how simple these are but they totally work. I can now just open a can and only drink a part of the can and know that when I go to refrigerator, the rest in the can still has fizz in it. Bought in all sizes.

Work just fine. Sure didn't need 18, but they do the job I needed them to do.

These are great! I ordered them because we enjoy Martinelli's sparkling cider for the holidays, and they used to have a plastic cap under the steel cap to close after opening to keep it fresh. But since last year they stopped supplying it. I called them and asked why, and was told they wanted to "reduce the amount of plastics"; supposedly being yet another company to give in to the "going green" fiasco. They had sent me a long, flat, steel combo cap remover and cover which just looked silly and you had to put the bottle in the refrigerator at an angle so you could get it under the ceiling. These caps are just so much better! Thanks for supplying them!

I bought these for a non -conventional use, although still as a cap. Works great as a carb cap and bowl saver. They have an absolutely air tight fit. Gave a couple to my niece and she used them for beer and said they worked great for that, the intended purpose. So yes, buy.

I use these to give my very small baby geckos their gecko food. They are able to easily find and eat the food, and these are easy to clean.
