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 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 means the formula flows through evenly, giving you a smooth line that doesn’t drag, every time. Swipe off with Milky Oil.’
