The ORIGINAL Tattoo Pen Sample pack. This pen is made for writing on skin pre-tattoo. If you have ever struggled with pens in the past like I have, such as clogging, disappearing while tattooing, or vague and inconsistent lines, then you will LOVE the Tattoo Pen. It is a solid brass housing holding a 1.6mm standard size, or 1.0mm fineline, ball point and carrying the best ink money can buy. They are the best quality of pens available for drawing a stencil on skin, but cheap enough to be single use and disposable for health standards and sterility.
