This voice changer accessory can make you sound like Ghost Face from the Scream movies. The accessory features a small black box with a speaker that requires 3 AA batteries (not included). A clip in the back of the speaker fastens easily to your belt or any sturdy piece of fabric. The speaker has 3 settings: monster, alien and own. A cord with an attached microphone fits easily into your mask. Don't just disguise yourself this year, disguise your voice too!
