What It Is: A waterproof high-precision eyeliner with a fine and flexible tip draws a buildable line, from the finest to the thickest, with an intensity that can be adjusted according to the pressure applied. What It Does: Infused with natural-origin charcoal, the formula delivers an intense matte finish for up to 24 hours. The line stays true and meets the challenges of the day. Its ultra-precise felt tip offers easy, buildable and smudge-free eyeliner application for a tailor-made graphic result of varying intensity as desired. For best results from the very first application, shake liner before use. Tip: Adjust the pressure to create a thicker or thinner line.
