Vampire Bites Piercing. This is a surface piercing located through the skin of the throat which looks like a vampire bite. A surface bar or curved bio-plast bar should be worn in the piercing. A variety of screw-fit add-on's such as gem balls can be used to change the appearance of the bar. These can be fitted without removing the bar. It is important to wear the correct size jewellery.
