i LOVE this eyeliner! i have insanely oily eyelids and EVERYTHING creases on it, even high end eye shadows with high end primers, but this is a DRUGSTORE EYELINER and it doesn't crease, turn into eye shadow, or fade off. i do cat eyes everyday and it never smudges, which is a plus. super super easy to use. i just wish that the brush that came with it were angled, but the small brushes are nice as well.
