Viscot skin scribe tattoo marker pen with dual tip. One fine point tip for fine details and lines, one large point tip for covering larger area. The ink in this pen is formulated for marking on skin and will go on easy and stay on. Although not using a non-smudge ink, this marker is ideal for smaller free hand pieces where smudging is not as much of a concern. These pens are specifically designed for skin marking purposes. They are commonly used in the medical, dental and tattoo industry.
