Medium brown: Best for medium to dark brown or black hair. A super-slim, waterproof brow pencil glides on smoothly and lasts all day thanks to Amazonian clay, which helps balance skin for perfect application and wear. Unlike thick wooden pencils that tug and look unnatural, this automatic fine liner is four times smaller than the average pencil, so it perfectly mimics actual brow hair for a more natural effect. Whether you’re looking to enhance your own natural shape or playing up the drama with a brow that channels Brooke, Audrey, or Sophia this dual-ended pencil also features a precision brush to help groom and tame unruly hairs into place. Powered By: Amazonian clay: Amazonian clay minimizes oil around the hair follicle to balance skin and keep pigment in place.
