The Silverback Ink® colours include a wide variety of very dark and strong shades which are certain to heal much more consistently than those you might mix and or dilute yourself in the hopes of finding the perfect colour. This is designed to be a blacker than black shade and is considered the darkest all-purpose black to be produced so far. This is a high quality, vegan friendly ink which is sterilized, so you can be completely confident not only in the standard of the ink but the cleanliness and freshness of the ink too
