So far, so good, but I've only used the eyeliner once. Has staying power. Would have been particularly exceptional--and would've received a five-star rating from me--if it had come with an eyeliner brush.
I've been using this eyeliner for years, but normally use the color Espresso Ink. This time I decided to try the Sepia Ink. I switched colors because I felt like the Espresso Ink was a bit too dark/harsh. I have fair skin and blue eyes. The Sepia Ink color is not as dark, and I can build the color. The reason this got four stars is for some reason it doesn't stay on as well when I sweat.
