4 Nars Eyeliner Stylo, $40
USING IT: The felt pen is a boon for beginners. The firm brush tip was comfortable and didn’t poke my eyes, although it wasn’t the most comfy in the lineup. It created the blackest line of the lot but left a stain even after I used both my makeup remover and cleansing foam on it. STAY-ON POWER: Only a third of the line had smudged on my extremely oily left eyelid; my right eyelid was fairly untainted.
