Urban Decay Mainline is a slightly cool-toned, dark blue with a matte finish. It is a permanent eyeliner that retails for $22.00 and contains 0.04 oz.
Urban Decay Mainline 24/7 Glide-On Eye Pencil (Eyeliner) ($22.00 for 0.04 oz.) is a muted, medium-dark blue with subtle, cool undertones and a matte finish. The pigmentation was opaque in a single stroke, which applied evenly to my lower lash line and didn't tug or pull on it during application.
The consistency was smooth, lightly creamy, and felt velvety but didn't feel so wet or emollient that it moved as it set into place. The color wore well for 10 hours before migrating slightly to the outer corner of my lash line.

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.
