The description "This waterproof precision inner rim liner is designed to brighten eyes and make eye whites look whiter, wide-awake and bigger."
The liner it is waterproof, it stays on all day on the waterline, I was very impressed for that. Unfortunately you don't get much product .
It almost looks like concealer when it is swatched.
Also, if you wear like to wear eyeliner in your waterline, there is pretty much no use for this.
