The Benefit BADgal BANG! 24 Hour Eye Pencil ($20) is exactly what you want to be wearing to a rock concert. The creamy, jet black formula glides on like velvet, while the built-in applicator easily smudges across the waterline for an intensely believable "I'm with the band" look. But once the colour is locked in, about 60 seconds after application, you can trust it's not going anywhere — headbanging (or mosh-pitting), be damned.
