The Spoolie Brush
The Spoolie brush is the best kept secret for brows. On one end you have the brow shaping tool, which looks just like a mascara wand with its soft bristles and tapered head. You use this to brush your brows into place, as well as distributing pigment when filling in. The Spoolie brush can also be used to remove mascara clumps and seperate lashes.
