This liner rocks! I also bought this liner in black and absolutely had the worst time with it- it kept breaking off, smudged, etc.
But this one-Graphite- works like a dream. It glides on smoothly, it stays put, I love the subtle look of the gray and it hasn't broken on me at all. I also enjoy the cooling sensation when you first put this on-it does feel like a liquid although it is in pencil form.
I would definitely repurchase this liner and will if I finish this one. I hope that the black liner I got was a dud and that this awesome gray liner isn't the fluke. I would also like to try the black plum liner as well.
