Mac Fluidline is an easy to use gel liner for precision application. It has a thick texture and it dries to a matte finish and there are really no limits to using it with either an angled brush or precision brush. It can used as an eyeshadow for smokey eyes or used in the waterline for tear-proof eyeliner. The one downside to this product is that after a while it will start to dry out, but no worries! pop it in the microwave for a few seconds to heat it up and voila!
