The ultra-fine 1mm precision tip makes it easy to create precise, hair-like strokes, detail the brows, and fill in sparse areas with natural-looking, buildable color. The smooth-gliding formula combines carnauba wax with castor, argan, and coconut oils to help pigment apply evenly with less tugging and breakage. The natural matte finish is waterproof, smudge-proof, transfer-resistant, and color-true for up to 24 hours. A built-in spoolie on the opposite end blends and diffuses color for a seamless finish.
