This is no ordinary stadium cup; it's a mind-bending, eye-catching, color-shifting phenomenon that will leave you wondering if your eyes are playing tricks on you or if what you're seeing is real. Rest assured, it's not an illusion. This 17 oz. stadium cup actually changes in color as it catches the light, thanks to a special coating that has an illusion effect. It makes a fun favor to match a mysterious Prom or Homecoming dance theme, like Masquerade, or a colorful theme, like tropical or Candyland. It's also perfect as a keepsake for your Senior Party, game day concession stands, or school events. And because it's made of durable plastic, it's ideal for outdoor use. Add your choice of one-color imprint to the front of the cup to customize it specifically for your school or event.
