Once you slide our thick BPA-Free silicone
sleeves on your 24 oz. wide-mouth mason jar, keep them on, put them in the dishwasher, and add all of our cool colors to your kitchen cabinet.
We've designed those circular holes in our silicone sleeves with a purpose, to let the mason jar breathe. You'll also find a drainage hole on the very bottom to allow water to drain after washing. Functional and cool.
Turn our lid upside-down for a perfect sippy cup mad from an all-American mason jar- works on any wide-mouth mason jars.
