New from eyeko this summer at Sephora are three shades of their Skinny Liquid Eyeliner.
These liners are smudge-proof and highly pigmented. You can create a thick or thin line with the precision tip, and they are really quite easy to use. Even for a liquid liner challenged person such as myself.
The shades being offered now are Black (jet black), Turquoise (bright aquamarine) and Olive Green (fatigue green).
