Senjo Color Tattoo Ink was developed to meet highest demands. The inks are so fine that they may be sprayed undiluted with fine 0.2 mm nozzles. They can be mixed together and look very realistic on skin. They may also be applied with a brush and can be diluted with 99 % ISO rubbing alcohol. A 15 ml colour bottle is sufficient for about 50 tattoos that stay on the skin for about 2–7 days.
