Complete your vampire Halloween costume with these Classic Deluxe Vampire Fangs. These vampire fangs come with everything you need to create a perfect fit. Just mix the liquid and powder customizing material together, put it inside the fang cap, push it up over your own tooth and hold for 5 minutes. The material then forms a permanent, rigid, snap-fitting mold of your tooth inside the fang for a tight, "clip-on fit". This one-time fitting process means the fangs can be taken off and put back on for years of use. These realistic vampire teeth are designed for people with average to larger teeth and may fit either canines or incisors or bottom teeth.
