1 X Disney Frozen Double Sided Mirror 25" Balloon (Each) Add a floating focal point to the party room with a Disney's Frozen Double Sided Mirror 25" Balloon. This huge balloon looks like a fancy trimmed mirror. On one side it has silver trim around a blue background and a picture of Elsa. The other side has purple trim and an image of Anna in front of the Castle of Arendelle. The balloon is shipped flat and requires helium, sold separately, to float.
