Silicone Chug Leak Resistant Lids for Regular Mouth Mason Jars

I've been using plastic protein shakers pretty much daily for years and finally got tired of using plastic. I found a brand that makes glass shakers with glass lids, but the seals on the lids are hard to clean and get moldy. So, I looked for a solution, and these lids have been awesome! I get questions all the time at the gym about these. If the lid is on correctly, I can shake it pretty hard with no leak, I can carry it upside down with no leak, etc. I will note that the silicon mouthpiece and the metal rim are two separate pieces, so you do need to make sure you have a good seal when you screw it on. I've also used it in the sauna. Great product!

This works perfectly for mixing shakes in the jar, easy to clean, no leaking!

I have used mason jars for everything for many years. I am not an internet surfer thus only recently found the tools I have been dreaming about!!!

They have all of the things I imagined, made better than I imagined!!

Thank you so much! Verna ;)

I am pleasantly surprised at how great this product is. I love that it has made by mason jar a convenient and leakproof beverage container. I am ordering another one as soon as I can!
