Chasing Fireflies Neon Invisible Stick Figure Halloween Costume Size 12. The neon green lights up the head, arms, and legs. The battery case holds 2 AA batteries and has a clip on feature. There's a button ton he case to turn the lights on and off. This stick outfit causes the wearer to be invisible at night except for the neon light outline. It's an easy costume to put on with the zipper starting on the back of the hood down to the bottom of the back. This well made costume starts at the ankles and fits great up to the hood. I have taken the 2 batteries out for shipping. This was a one time use favorite halloween costume! It's in excellent condition.
