I'll never spill the (coffee) beans. You could say I'm pretty tight lipped-all thanks to my leakproof slider lid. But besides keeping your caffeine safe, I also keep drinks hot or cold and my ohhhh-so-smooth spout delivers the best sipping experience you'll ever have. Cup holder friendly? That's a given.
