NARS has introduced their version of the liquid eyeliner pen, the Eyeliner Stylo. Available in three shades - Nuits Blanches (a shiny black), Blue Bayou (a teal blue), and Nabucco (brown) - this felt-tipped pen allows for smooth and even application. The precision tip is designed to easily deliver a thin or a thicker line, with intense pigmentation and a quick-drying formula.
I am now very interested to see how this liner pen compares to others on the market. MAC offers their Penultimate Eyeliner in Rapidblack ($16.50 at MAC stores, counters and online at http://www.maccosmetics.com/) and Stila has recently introduced their Barbie Loves Stila Liquid Liner in black ($20 at http://www.stilacosmetics.com/). The Eyeliner Stylo in the teal shade looks particularly gorgeous. I can't wait to my hands on one to try it out!
