These brush pen skin markers from Edding are a professional tattoo supply and have been developed specially for use within the tattoo studio. Using a water based ink, they will not irritate or damage the skin when used in preparation to tattooing. They are also suitable for sensitive skins as there are no harsh or long lasting chemicals used in the formula. Ideal for editing stencils and creating freehand designed directly on the skin, these markers will no doubt prove very useful in the tattoo studio. There is also a large selection of colours available, meaning you can separate different sections of the design for various techniques or styles you may plan on using.
