Urban Decay Black Magic 24/7 Glide-On Eye Double-Ended Pencil Set ($39.00 for 0.08 oz.) includes four, double-ended eyeliners. Each side is 0.01 oz., so it's really the equivalent of 2 full-sized eyeliners, though you're getting eight shades for the price of two. These are all previously released shades with two being brought back in this set (Black Market and Tornado) and the others are permanent. Urban Decay's formula is long-wearing on me (eight to ten hours), and it is a waxy, glide-on formula that doesn't tug at the lash line, but some shades require two to three passes for full color coverage.
