MAC Fluidlines and I have been best buds for quite some time now. They are my first gel eyeliners and are a dream to apply! All you have to do is dip the brush into the product, pull your skin taut and they glide right on. Although they apply a little moist, they do dry fast and stay put all day. Plus since they come in bright, funky colors, you can also use them as an eyeshadow base. Highly recommended!
I have Sweet Sage, Blue Peep, Blacktrack and Delphic and I am planning on getting more!
MAC Fluidline is available at Nordstrom and MAC stores and counters.
