Are your eyebrows just a little too Cara Delevingne for your taste these days? Benefit cosmetics is offering to fix those puppies up for you tomorrow inside their brand-new PrimpMobile, which will be parked in front of Madison Square Park from 10am through 4pm. The best part? It's free, free, free.

Benefit can tweeze or wax away the strays, fill in any empty spots, and tint for your perfect match. If needed, they can even start you off with a clean slate with a brow mapping—figuring out the best arch for your face shape.

Outside of NYC? Check out the link below to see how to get the PrimpMobile to come to your city.
