What it is: An easy-to-use black liquid eyeliner with a brush tip for precise definition, in a smudge-resistant formula. The pen’s brush tip was designed with flexible fibers that hug the curve of the lash line for easy application. Densely-pigmented, buildable formula dries quickly so it doesn’t smudge and stays put for up to 12 hours Internal ball shaker lets the formula flow through evenly, giving you a smooth line that doesn’t drag, every time. 0.47 ml / 0.01 fl oz
