Skin Pens are a specific type of pen used/applied to skin, to create a permanent image. These kinds of pens are normally used by either surgeons before proceeding with surgery for either medical purposes or beauty surgeries. Also, they are often seen used in tattoo parlours before applying the actual permanent ink.
