Blinc's Kiss Me Eyeliner doesn't do all that it claims. Sure, it stays on significantly better than other eyeliners out there, but that's only provided that you don't touch it. Contrary to what it says on the packaging, it DOES come off with just pressure alone. Slide your finger over it and it will sort of flake/peel off. Some reviewers say that they were able to sleep with it on, but when I myself tried to do it, it was partially rubbed off the next morning. It doesn't smudge or run at all however. I agree with some of the other reviews I've read that say you should abide by the instructions given. Apply a thin layer to a clean eyelid and there shouldnt be too much fuss. If you need to put concealer on your eye area do it afterwards. I liked that it dried to a matte finish unlike some other long wearing liquid eyeliners out there that tend to turn out shiny. It's very easy to take off and doesnt leave any annoying residue. Just don't touch it and it will stay on all day.
