I love MAC products it can definitely live without this. It was very difficult to apply and went on poorly. I used it one time and won’t try it again. Total waste of money for me.
I have this liner in the brown color and it is great, Easy to apply, doesn't flake and doesn't smear, I threw out all my old liners and figured I would replace with the black and follow up with more later on. The blackish color I returned because it did all of the above and for some reason even after using two makeup removers on it before bed I woke with some still under my eyes
