Cover almost any glass with the first ever universal beverage cap. The Cool Cap was originally invented as an alternative to plastic tumblers. The Founder of GreenPaxx is a former critical care cardiac RN who did not want her family exposed to endocrine disrupting plastic or toxic metal cups. She quickly realized it fit almost every single cup she owned, making it the most versatile product for all ages, from children all the way to the elderly, who often need a covered glass. Because it fits most regular drinking glasses, you do not have to worry about washing the same cup every day. Just rinse your Cool Cap and use another glass!
It has three underside rings that stretch to fit all cups from 2.75 – 3.75 inches. Made from 100% non-toxic food-grade silicone, it allows you to create a spill resistant cup out of almost anything you already have in the house. Take your drinks, juices and smoothies in the car, the pool, to the soccer game, and keep at your computer or bedside to prevent spills! It keeps beverages carbonated longer and even keeps drinks cold longer in the sun (silicone is non-reactive and does not conduct electricity or retain heat or cold like metal)
