Swatches and pics:
I tested out how it smudges on my hand. It didn't fare so well... But on the eye it actually lasts pretty well. I wore it for several hours before washing it off and it didn't smudge.
This is what was left behind on my finger from smudging it. Again, you can see how much sparkle is in it!
This lasts really well on my eyes. As for application, it doesn't glide very well. You do have to do shorter strokes because of this, but it's so pigmented that you don't have to go over your lashline multiple times. All in all, I really like this eyeliner. Plus it's only 99 cents!
