With its patent-pending design, the COOL CAP has two rings on its underside that can each be stretched to fit several different sized beverage rims. It securely fits almost all drinking glasses, with the small exception of glasses whose rims are close in size to their base.(flute-like glasses) It even stretches to fit square rimmed glasses! The average size glass rim it will fit is 3.25 inches to 3.75 inches. The inner ring fits the average pint glass for reference, so will not fit glasses that have a much smaller rim than a pint glass. It also fits all wide mouth mason jars.
2) Will GreenPaxx products melt, warp or leach chemicals if I leave them in my car?
GreenPaxx products are made from 100% food-grade silicone, an inert material that can safely withstand temperature ranges of -20°F to 450°F without degrading or warping. And because the silicone inGreenPaxx products does not contain any fillers like some silicone products do, it does not contain any harmful substances therefore will never leach any.
3) Can I use my COOL CAP and COOL STRAWS for hot drinks?
Keeping in mind that you should always use caution when drinking hot beverages or soups, you can absolutely use them. Be sure your drink has cooled sufficiently then sip away!
4) Do I need special cleaning tools to clean my Cool Straws?
Unlike other reusable straws, GreenPaxx Cool Straws are made from non toxic food grade silicone, a naturally non stick material that repels debris, making them super easy to clean. In case you forget to rinse them immediately after use, just run them under warm soapy water while kneading the length of the straw and any stuck on food should easily rinse off. No pipe cleaners required! They are dishwasher safe but hand washing is recommended to prolong the life of the products.
