Fangs

Need to be more beastly? A touch Vampiric perhaps?
A pair of fangs (plus a tiny vial of dental adhesive) make great addition to your ensemble, breaking up the straight line of human teeth which is about the only part of you which is visible under a mask.
Obviously, they are the only specialist costume you really need for a live Vampire character in a modern day setting.
Easy to wear, and are easier to speak clearly while wearing than other types of fang sets.

These MUST be removed to eat or drink.
For use by over 14's only.
Keep away from children, mostly because of the possibility for choking, partly because they may attempt a neck vein puncturing bite and are notoriously poor at pulling their blows...
