18 Silicone Reusable Caps for Home Brew & Soft Drink Bottles, Soda & Wine, Multi-color

Perfect for keeping drinks safe from wasps. Fits most soda bottles.

I absolutely love these !!! It keeps bugs out of your beer , soda , or anything else that they try to crawl into when you're at picnics outside !!! I bought extra so i can keep them in my suv so when I go out . I can use them at a restaurant for my bottled drink !!! I like to keep things safe from strangers thinking they can add to my drink

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.

These fit well and is as described. The order shipped fast and I might have to buy more since my friends and family are "borrowing" mine.

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=1 UPDATE 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.
