The applicator in this stuff is awesome! I can get a great cat eye with it. It's water proof. But don't make a mistake when you're applying it because you will have ruined your makeup. You can't just wipe it off and try again.That said it does last a long time. I have fallen asleep with it on and still had perfect eyeliner in the morning! But I wouldn't suggest buying this if you don't have a good eye makeup remover on hand.
