Sometimes you know that favorite mascara gets a little chunky and gritty. Well this is what I use to fix it. Everyone needs one just because it serves more than one purpose, i use it one my brows with brow gels because some wands that come with the original products are just too small, which makes it and all day process! I use it to separate and coat my lashes. I also use it when waxing clients brows for accidental drops onto the hairs to remove excess wax. EASY PEASY!!!
