I use these on my lava lamps when I pop the cap to refurbish them. They work great to keep the lamp capped until you are ready to put the metal bottle cap back on

These caps work really, really well when actually used for their original purpose. Specifically, to keep bottle contents fresh if the consumer can't use it all in one sitting.If you put these on a beer bottle with a screw cap, it is physically impossible to create a 100% water tight seal. Users should have a modicum of common sense to understand that threads create air gaps. Use these on a bottle that require an opener, they create a nearly airtight seal. There is no reason to ding the product because the user doesn't get the concept.

Fits glass beer bottles perfectly. Great value for cost. Easily washed, easy to use, no leakage when applied properly when bottle tipped on its side. Fits snuggly, good quality and function.

Exactly that. Not a great fit. Plus you will have the unpleasant chance the rub lids pop off.

I bought these bottle caps to function as tiny feeding dishes for my baby crested geckos and gargoyle geckos and they work like a charm! They're cheap, reusable, and perfect for any reptile breeders working with small geckos feeding on powdered diet.

I make Colloidal Silver for all my friends using dark colored bottles from various sources. These flexible caps have given me lots of help giving a gift that looks good and keeps the bottle secure between uses.

UPDATE 2 20 24: I'm done with these. The hack seemed to work for a while but the fix is not good enough. They still pop off if you don't remove the lid periodically to release the pressure. I recommend a different type. I'm going to try these instead: https://www.amazon.com/dp/B09MW46YS1?ref=ppx_yo2ov_dt_b_product_details&th=1UPDATE 7 10 23: Lid popped off again so I took a corkscrew and made an even bigger hole. The material though comes back together that you can't see the hole. I've had no further issues with tops popping off, and still no leaks.ORIGINAL REVIEW: I just use mine to cover my beer sitting in the bar, outdoors or in the car (I don't drive, I'm a passenger). The carbonation in a drink will cause the lid to pop off, as do frozen drinks (I opened a beer at home one day and it froze before my eyes. I covered it with this and the lid popped off, so I recovered it with its original cap until it melted enough to drink).My solution, was to relieve the pressure by poking as many holes as possible in the lid with a push pin. I sterilized a push pin, put the silicone lid on the bottle and poked away. When you're done, you won't see any holes so it will still keep critters out but so far, the lids haven't been popping off.I haven't tested its leakproof ability. It doesn't fit my Modelo bottles very snug, so I'm sure it will spill but definitely not as much most likely, Overall, I'm pleased with this product once I applied my simple hack.Perhaps the manufacturer will consider a version with vent holes. I will buy these again as needed, and just poke my own holes in the lids.7/3/23 UPDATE: I turned my beer upside down with the lid on and push pin holes poked in the lid. NO LEAKS, NOT A DROP. Definitely a winner and a keeper. The hack is working, no lids popped off yesterday in true life bar situation. Wonderful.

I was looking for a cap to put on a glass bottle when I only wanted to drink a small amount. These silicon caps were bright colored (so they are easy to spot in the drawer) and they are made from silicon so they clean easily. They have worked out well. They keep the fizz in my coke bottle and they keep a bottle of beer from going flat. Inexpensive and easy to use.
