It's like a sippy cup but for big boys and girls! And not just for big boys and girls, either, but for adults too. Able to hold up to 16 ounces of liquid, this Superman Trio Plastic Flip Straw Cold Cup is the perfect thing for you to carry around your cold drink while on the go in DC Comics style. Not only does it feature a great image from a classic Justice League comic with Superman, the Flash, and Batman rushing into action along with the words, "At last the trio springs into action. Superman, Batman, The Flash... In the face of danger superheroes unite to battle any threat to the Earth, day or night..," but it also boasts a double-walled design to help keep your drink cold plus a cool flip straw to help keep you from spilling!
