Ear piercing instruments, sometimes called "ear-piercing guns", were originally developed for physician use but with modifications became available in retail settings. Today more and more people in the Western world have their ears pierced with an ear piercing instrument in specialty jewellery or accessory stores, or at home using disposable ear piercing instruments. An earlobe piercing performed with an ear piercing instrument is often described as feeling similar to being pinched, or being snapped by a rubber band. Piercing with this method, especially for cartilage piercings, is not recommended by many piercing professionals and physicians, as it can cause blunt force trauma to the skin, and takes far longer to heal than needle piercing. In addition, the vast majority of ear piercing instruments are made of plastic, which means they can never be truly sterilized by use of an Autoclave, increasing chance of infection exponentially. In the case of cartilage piercing, doing it with an ear piercing instrument can shatter the ear cartilage and lead to serious complications.
