Blinc’s Tubing Liquid Eyeliner is VEGAN and GLUTEN-FREE. It creates an ultra longwearing, jet-black, water-resistant color layer on your skin. This formula is based on Blinc’s pioneering tubing technology. The beautiful color layer binds to your skin and can't fade, flake, smudge, or run, even if you sweat, cry, or rub your eyes. The elongated handle provides ultimate application control, while the precise brush tip enables you to craft anything from fine lines to dramatic, bold cat eyes.
