Well, there goes the neighborhood! With the Jason Blister Kit Costume Adult, you can bring the terror of the Friday the 13th horror films to life. This costume features the iconic Jason hockey mask, a green blood stained shirt, and a blood stained machete. Get a pair of jeans and a container of fake blood, and you'll be ready to cause all sorts of mischief on Halloween night. This officially licensed costume is a one size fits most, so you should be able to fit into it nicely and wreak havoc. Just watch out for Freddy Krueger. If the movie Freddy Vs. Jason taught us anything, it's that two horror figures should never meet in person. It never ends well for all those innocent bystanders.
