This weightless eyeliner pencil embodies the new Thermo-Sensory Technology, which transforms from solid to liquid upon contact with the skin, creating a flexible, waterproof coating that lasts up to 24 hours. The ultra-fine lead of this pencil is very convenient for makeup along the inner lash line and allows for precise contouring. Bright pigments of the lead provide a rich, matte color. It does not smudge, resistant to tears and moisture.
