What It's Used For: Spoolie brushes serve a few different purposes. They're great for removing clumps following mascara application. They are also extremely useful when it comes to eyebrows, whether it's for distributing pigment for bold brows or just grooming an errant hair.
What It Looks Like: Take a look at your mascara wand. It's fitted with about an inch of bristles that cyclone to a point. A spoolie brush follows the same design, just with a longer handle.
Why You Need It: Ever had a clump you couldn't crush? Thinking about giving bold brows a go? A spoolie brush is a necessary tool for both of these issues. Simply take a clean brush and wiggle it over your brows or up your lashes to keep everything looking clean and neat.
If you think you need a spoolie brush in your life, we're loving Laura Mercier's Brow Grooming Brush ($22).
