This product does not work good at all. My son’s water bottle now leaks and it never use to with the original parts.

I actually got these to help seal up a whiskey infusion bottle that came with a weak gasket and it works perfectly. I paired it with another larger gasket to fit the unique shape of the infuser and this formed a perfect seal. It's always great when you take a shot with a product that you're using for a different purpose than intended and it works out. The seals feel very durable and I think they are a great value. The tweezer-type tool that was supplied with the gaskets also works well for removing gaskets from my son's water bottles when I clean them.

These work! They fit my son's Thermos 16 oz. Funtainer. My son's original silicone pieces of his Thermos got a little mold. Even though it washed off, mold is extremely toxic and since silicone is porous, I didn't feel comfortable allowing my son to keep using his Thermos. So I was so happy to find these replacement parts. They fit perfectly!
