Review (4/5): It lives up to the hype
This eyeliner has great staying power, and doesn't smudge if you itch your eyes by accident. If you do rub your eyes it just kind of balls up and disappears, so even though on its own it does not budge, it's very easy to remove. I find that application is a little bit awkward, the pen doesn't draw as smoothly as I would like and the felt tip occasionally gets some stray fibers that can muck up the line. However, on the formula alone this is still a good eyeliner for the price.
