Reusable Beer Caps, Silicone Rubber Bottle Caps (Pack of 18), Ideal for Home Brewing Beer, Soft Drink,Soda Bottle Kitchen Gadgets

I made some water bottles from cleaned/sanitized beer bottles- and these little lids actually do work. I doubt they would work on any carbonated drinks though. Once put on tight- I shook the water around and put the bottle on its side- no leaks. Put the bottle in the fridge to see if the lid would stay on- did until I took it out of the fridge and opened it up.They are small and easy to lose- the cool container they came in keeps them easy to find. I would buy again.

Bought these for our cruise. Had the drink package and thought they may open our bottles. This did what I needed. Glad to have them. And they are reusable and come in a great case

They effectively do the job.

I liked them, but mine kept popping off my beer bottle due to the carbonation. It was shortly after opening the beer bottle, once my beer settled it stayed put pretty well.

Good to keep debris out, but won't hold the fizz in.

Keeps the bugs out of your beer and with the different colors its easy to tell whos is whos. So you don't drink anyone elses! It fits the rim great and its easy to clean.

The caps are much better than the whittled corks that I was using. I am repurposing beer bottles to hold my homemade tinctures but the corks made the bottles too tall to fit on the shelf. These caps solved the problem.

They look cute and go on easy. No leaks when turned upside down, or when stored on its side with liquid in the bottle. Highly satisfied with this product.
