Color Envy Waterproof Liquid Eyeliner in Black Diamond is my go-to eyeliner when I'm wearing false lashes (which is most of the time if I leave the house), and I will never be without it. It's sometimes hard to find, so I order it on their website and order several at a time so I never run out. It has just the right size and shape brush for the perfect line. And, the stuff does not budge, I mean it. Does. Not. Budge. It has to be removed with some good eye makeup remover. I've found that micellar water works best for me, even better than my best remover, because if I just put some on a cotton round, fold it, and hold it on my eye several seconds, then I do not have to rub my eyes very much at all to get all my eye makeup off (even stubborn mascara). I love this eyeliner. It's easy to use; once you get used to the brush, it's really easy. You do need to shake it before you use it, and, I like to store mine upside down. This is a 5 star product for me. It's not $45.00, or a high end name, it's less than $5.00, and I love that! That lets me buy a high end product sometimes.
