Panthera’s Smooth Finish Black Ink is part of tattoo artist Ralf Nonnweiler’s greywash series. Nonnweiler’s Smooth Finish contains a minimal amount of pigment, making it ideal for promoting contrast and executing light, subtle shades during the final stages of tattooing. This highly diluted Smooth Finish also allows artists to saturate the lightest aspects of his or her tattoo for a soft gray hue that lasts even after the healing process.
