I normally love Mehron products and this looks phenomenal so I really wanted to love this, and I do - but not as much as I had hoped. The formula is a nice opaque black, it applies easily, dry time is a few moments (but that is typical for a liquid liner), it removes nicely with makeup remover (some products are too stubborn for instances where makeup needs to be changed). Unfortunately it starts crumbling off in chunks about 5-6 hours into wear for me. I find that it holds up well for a fast shoot, it's nice for a 3 hour event, but I cannot use this on brides (even if I set it with duraline or a shadow). It doesn't have enough longevity and crumbles too much.
