The most common request we have is for the blackest black possible that won't turn blue. We've never given up trying to make a black eyeliner color that goes into the skin easily, is MRI safe and doesn't turn blue. What you should know is that all blacks have blue undertones if they are pure. So those undertones need to be neutralized in order for the black to stay black. That is our goal with StaBlack™ BLACK ICE. We hope you enjoy it. Questions? Call Toll Free 888/452-4956. A bit warmer than Black Silk. Very, very black. Keep your needle direction toward the eye so you don't get a halo or splinter effect with this pigment. Questions? Toll Free 888/452-4946. 1/4 oz. $20.00 Contains Carbon Black.
