Color-size your next school event with this unique Rainbow Confetti Mood Cup. It's a great favor for Prom or Homecoming, or can be filled with an ice cold beverage for Homecoming or your Senior Party--and then students can watch it change color! The 17 oz. plastic cup comes white, with a slight swirled marble look, but changes to a colored confetti (featuring colors of red, blue, green, purple, and orange) with ice cold liquids. You can even customize this cup, too! Simply add your one-color imprint to one side of the cup to customize it for your Prom theme or school name. 5" high x 3 7/16" diameter. Top shelf dishwasher safe. BPA free.
