With this Mood Magic Color-changing Tumbler, it's like getting two custom tumblers in one; because it changes color when you add an ice-cold beverage. Made of sturdy polypropylene, the 22 oz. travel tumbler includes a snap-on, spill-resistant lid and a 9" straw. Add your choice of one-color imprint to the front of the cup to customize it for your school or event. This fun mood tumbler makes a great school or team fundraiser or a cool Prom or Homecoming dance favor to match a tropical, 1980s, or neon theme. BPA-free. Made in the USA.
