What it is: An ultra-fine brow shaping and defining pencil that draws incredibly natural hair-like strokes that last up to 12 hours. What it does: It transforms shapeless, undefined brows with just a few flicks of the pencil. The custom, ultra-fine tip makes adding detailed definition to your brows easy, and its rich, waterproof formula is ideal for spot-filling sparse or over-tweezed areas. It's smudgeproof and firm enough for precise application, yet it glides on effortlessly to bring symmetry to your brows and your entire face. How to use: Hold the pencil along the custom control grip. To shape brows, use longer, horizontal strokes along the base of your brow. Fill by drawing short, upward strokes in the direction of your natural hair growth. Gently brush through brows with the spoolie to evenly blend color and tame hairs. 0.002 oz.
