Original Cuppow Regular with Straw-Tek is a travel lid designed to fit mason jars with standard sized mouth so you can take your hot or cold drinks with you as you go! Cuppow was designed, manufactured, and packaged in the USA. It’s a BPA-free and phthalate-free eco-friendly travel lid; and, when the time comes, it is recyclable as well. Replace your disposable coffee cups with a mason jar plus Cuppow! How to use it? Just take a mason jar, and replace the standard metal lid with the BPA-free Cuppow, add the ring to secure it, and enjoy water, your tea, coffee, etc, without sloshing. If you are needing to cap off the jar (in order to, say, throw the whole thing in a bag), just add the canning lid under the Cuppow and remove when you arrive at your destination. The Cuppow makes a great gift for friends and family who love their mason jars, are concerned about reducing waste, and/or who love a great conversation starter. Cuppow also works as a great next step for little folks who have graduated from their sippy cup and for those not-so-little folks who are prone to spilling while they drive or try to drink and walk at the same time.
