This is a Star Wars Clone Trooper voice changer helmet. I am selling it to organize my collection. This is a helmet that you can actually wear and play with. By pressing the button on the side of the helmet, you can play English lines, or speak with the built-in microphone as if you were talking to your comrades on the radio. (Requires 3 AA batteries, operation confirmed) I bought it new and stored it in a dark place for a long time, but there is some discoloration of the plastic due to aging, as well as scratches and dirt. Please understand this before purchasing. Thank you.
