Hardly smudges, love the gray color, easy to use, glides right on, retractable,
But
Pricey, but I guess it's worth it.

These have become my go to liners every day.
They glide on super easily, stay put all day, and best of all come off with no smudges at the end of the day.
The colour pay off is great. Oscar Fish (brown) and Moray (mossy green) are my favorites to use with my green eyes.
All 5 have a just bit of shimmer to them which adds dimension and makes the colours pop. I especially like it in Stargazer (black).

The only drawback which I noticed (and have also noticed in other reviews) is the packaging. It's a twist up pencil, which is great because there's no need to scramble for a sharpener, but sadly it doesn't twist up very well. I have to twist back and forth a few times before the product comes out.
Other than that, love these!
