Ear piercing gun. The most common design uses a spring that stores potential energy when part of the ear piercing instrument is pulled back. Pre-sterilized starter studs and matching friction backs are typically provided in pairs by the piercing gun manufacturer in sealed containers. A starter stud has a point that is designed to penetrate the earlobe when the mechanism is pulled. You can get these at beauty supply stores. This is in excellent condition.
