Anastasia Beverly Hills Darkside Waterproof Gel Liner is a professional-quality retractable, waterproof gel eyeliner pencil that offers intensely black pigment with a matte finish. Use this smooth, long-wearing, full-pigment eye makeup formula to tightline and add intensity to any eye makeup look. While the retractable tip on this matte eyeliner pencil helps ensure better control and prevent breakage, the true-black gel formula stays put all day and doesn’t run.
