NARS Sorrento Kohliner ($26.00 for 0.02 oz.) is a medium-dark, red-toned brown with warmer undertones and a matte finish. It had semi-opaque color payoff in a single stroke, which was consistent with the eyeliner being described as "buildable" by the brand, as it was opaque in two to three layers. The texture was fairly smooth, though it seemed a bit drier than other shades I've tried in the Kohliner formula. The eyeliner stayed on well for six hours on my waterline and eight hours on my lower lash line.
