This costume is perfect for any Disney or Toy Story fan! Light weight Battery pack keeps this costume inflated. On and off switch allows the wearer to control. Kids and adults alike love this costume!!! Includes purple head piece and costume with inflator. I wore this once to school (I’m a teacher) and put it back in the package. Got it out and tested the inflator. Everything works perfectly! Smoke free home. One size fits most adults men or women! Takes 4 AA batteries that are not included for safety reasons.
