M·A·C 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!
MAC Fluidline is available at Nordstrom and MAC stores and counters.
