Don't we all just act on the assumption that clowns are utterly mad all the time? I don't know if we need to press that opinion too intensely hard. It seems to be a fairly well accepted idea. Anyways, while I'm sure you've seen plenty of clown masks before (either at a store or a party or in your nightmares), but I bet you've never seen one that has an actual moving mouth. The Insane Clown Mask has "Ani-Motion Mask technology, which basically means that when you move your mouth, the mask's mouth moves with you. Pretty cool. Also, horrifically terrifying. It's like staring into the gates of hell. The perfect Halloween mask.The Insane Clown Mask is the mask of a madman and the perfect item to top off whatever horrifying outfit you've picked out for this Halloween.
