Pro Tip is everything you want in a liquid liner (it draws the sharpest line, comes in the truest black, and doesn’t budge) with no tricky, time-sucking application (redoing the line, getting it even, and using all the makeup remover). The pen’s brush tip was designed with flexible fibers that hug the curve of the lash line, allowing for precise definition. Its densely-pigmented, buildable formula dries quickly so it’s smudge resistant and stays put for up to 12 hours. Plus, an internal ball shaker lets the formula flow through evenly, giving you a smooth line that doesn’t drag, every time. Swipe off with Milky Oil.
