INTENZE Products are proud to present a new black & grey tattoo ink set formulated by legendary tattooist Mark Mahoney, the ""founding father"" of black and grey tattooing. This is the formula and shades of black & grey that Mark Mahoney himself uses while he tattoos. The result is an unbelievable black & grey system of tattoo ink that is perfectly suited for black & grey portraits, lettering, religious tattoos, and Cholo artwork made popular in Southern California. Mark Mahoney is a tattoo icon and the purveyor of the Shamrock Social Club on Hollywood's sunset strip in Los Angeles. He came up in the old school ways of tattooing and broke boundaries with his unique style and impact on the California tattoo scene, which has influenced the entire world.
