Have a bloody good time with this horrifying prosthetic. The realistic stitched design grosses out friends and keeps strangers guessing. Surround with bruise makeup or let the wound speak for itself. This choice is a surefire way to transform any costume into a ghoulish life of the party.
You'll probably want some blood gel for extra realism and you will need some Spirit Gum or other skin adhesive to attach the latex appliance to your skin.
