What it is: A waterproof, metallic liquid eyeliner in twist-up pen. What it does: Create an intense single stroke of color with a tinge of pearlescent sparkle. The easy-to-use, precision brush can be used to draw the perfect line for subtly accentuating the eye or for a dramatic, winged-out look. The versatile formula doesn’t flake, fade, or budge, making it ideal for use as an eye shadow, highlighter, or brushed onto lashes over mascara for a dip-dye effect. What it is formulated WITHOUT: Parabens. Sulfates. Phthalates. What else you need to know: "I love the pigment and fluidity of these eyeliners. The fine brush makes them easy to use and they're indelible, which makes them great for use on the lower lid and brushed over lashes." -Top Make-Up Artist Lisa Eldridge.
