Urban Decay Oil Slick is a slightly cool-toned, dark black with a glitter finish. It is a permanent eyeliner that retails for $22.00 and contains 0.04 oz.
Urban Decay Oil Slick 24/7 Glide-On Eye Pencil (Eyeliner) ($22.00 for 0.04 oz.) is a soft black base with flecks of silver micro-glitter and pearl throughout. It seemed to flash almost bluish-teal at times to my eye. The texture was more emollient than most shades in the range, so it didn't have as even of an application without being layered.
It had medium coverage in one pass, which I could build up to full coverage with a full second layer. I didn't feel much of the glitter/sparkle during application, but it actually contains plastic (PET) glitter in it, so I would be cautious using it near the water line for those more concerned about glitter. It lasted decently for eight and a half hours before migrating slightly to the outer corners of my eyes. Uzi has a similar effect with finer shimmer, has more payoff, and doesn't contain plastic glitter--a great substitute, IMO.
