5 Clio Waterproof Pen Liner Kill Black, $22.90
USING IT: The firm felt brush was easy to use but wasn’t comfortable. It felt pokey, so I had to go slowly. It dried quickly and I liked its intense, slightly glossy black line. STAY-ON POWER: Lines were just slightly smudged at midday but after 15 hours, onethird of the line had disappeared although the winged flicks on the outer edges were intact.
