18 PCS Silicone Rubber Bottle Caps, Reusable for Home Brewing Beer, Soft Drink, Wine, Soda - Kitchen Gadgets (Multi-color)

These handy little tops are fantastic. It makes it possible to re-cover just about any bottle and reuse the glass. I fill my Sanpellegrino water bottles, that came with a disposable cap, with filtered water and keep them in my fridge. Very handy, and saves perfectly good bottles from going into a landfill. I was shocked to discover that I can even lay the bottles on their sides and they won’t leak!!

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

Ever go to a bar and they give you 2 bottles as part of their 2-for-1 happy hour? Use these to keep the second beer fresher while you work on the first beer.

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.
