Ultra Ink Liner is a vegan liquid eyeliner with ultra-black intensity and a flexible felt tip, delivering waterproof, smudge-resistant long wear in 1 stroke—even over bold eyeshadow. We call it the one-swipe wonder of felt tip eyeliner for a reason! Ultra Ink Liner is the final version of “Liner X,” the crowdsourced felt tip liquid eyeliner that makeup lovers everywhere obsessed about. “Liner X” was born after KVD Beauty discovered a brand new long-wear eyeliner innovation in the lab, and brought it to the market ASAP, so our eyeliner fans and experts could experience it first and give their honest feedback. We used that feedback to make this already incredible vegan eyeliner even better, with a newly perfected tip for a better application experience.
