To apply, use the spoolie brush to comb eyebrows into shape, then use the ultra-fine nib to shape and fill in sparse areas. For the finishing touch, use the spoolie brush to comb through your brows once more to help blend for a natural finish. You'll find that it's easy to remove at the end of the day, too. Get full, naturally defined brows that last with Brow Pro Micro Ultra-Fine Precision Pencil.
