    My new fave mascara

    Love how feathery, full and long my lashes look. Incredible staying power. I wore them through 2 workouts and teaching 2 online cardio classes with zero flaking. Great value for the price; I only needed one dip for both eyes and my lashes were fully-coated. I can't review the lash-boosting properties as I have only been using it for a week.
