Our unique Good Vibes 2-D Mirror Ball Kit is a funky hanging decoration for any 1970s Prom theme. It's also a unique alternative to a three-dimensional mirror ball--this one is big enough to be used as a photo op for selfies! The 2-D mirror ball is made from printed cardboard, white cardboard, and comes with black thread for easy hanging. Once completed, the mirror ball measures 5'10" diameter x 3" deep. Assembly required.
