Black Jack (01) Eye Pencil ($30.00 for 0.01 oz.) is described as a "black." It's a deep black with a semi-matte finish. It had good color payoff in a single stroke, and it was buildable to fully opaque color. The consistency was creamy, so the pencil glided on easily without skipping or tugging at the lash line. It wore well for eight and a half hours, and it even managed the water line for six and a half hours. It started to thin slightly but still looked quite nice after ten hours of wear--and no smudging or migration. It's a basic black eyeliner, which is essential for each brand to have within their range, but it also means there are plenty of similar shades on the market.
