NOTHING extremely special about this thing, but it works. It does what it's supposed to do, but it ain't spectacular. That's all.

my favorite thing about this eyeliner is that it doesn't have to be sharpened, it's retractable. i like how it keeps a petite and precise shape, because that makes it ideal for tight lining and lining your water line without scraping your eyeball (ouch!), etc. it's fairly creamy, creamy enough for smudging against your lashline, but it won't rub off too easily.
i only wish it was a little more pigmented. the staying power is great, even in the waterline. i usually get about five or six hours out of it.
* a similar liner is maybelline unstoppable, and i think this one trumps that. in terms of pigmentation, this can't beat things like milani's liquif' eye or urban decay's 24/7 liners, but it is a competitor for staying power.

here's a swatch of mine in "black."
