It's a standard pencil- I almost can't stand twist ups anymore...
What I like most is the colour- its not a plum or a berry, just purple:
This is a pretty decent eyeliner, but I find it unwearable on my waterline, it's just too irritating. It does pull a little bit too. But I really like how it's very pigmented even on my eyelid. I don't think it's the smoothest or creamiest eyeliner by any means, but it goes on with a deep colour in just one swipe.
It didn't last anywhere near their 16 hour claim on me either- it looked good at 8 hours, fading at 10, gone by 12. Overall, the colour is what sold me but I don't see a reason to buy another.
