Our award-winning, bestselling, and waterproof 24/7 Glide-On Eye Pencil comes in an insane range of shades, from daytime neutrals to electric hues, and five finishes—shimmer, satin, matte, metallic, and glitter. This eyeliner goes on smoothly, stays soft and super-creamy for blending (about 30 seconds), then dries to a long-lasting finish that won't budge. Line your eyes with a hint of color or opt for a graphic, dramatic look. Use them solo or combine with Urban Decay eyeshadows for more intensity. Created with 50 percent moisturizing ingredients suspended in a waterproof formula, 24/7 Eye Pencil gets a boost from vitamin E, jojoba oil, and cottonseed oil. Use the Grindhouse Double Barrel Sharpener to keep your pencils always sharp.
