This curved Brow Shaper Brush is the ideal tool for softly filling sparse brows for a natural look. The ultra-soft bristles help create the look of real brow hairs. Use with Precision Brow Gel or Eyebrow Cake. Pro Tip From Illamasqua Head Of Artistry - Pablo Rodriguez: Just add some colour to your brows, going back and forth over them with this brush. Quite sketchy, super easy. Play with the shape of your natural brows to make them straighter or even more arched.
