It's smudge proof and water proof yet was super easy to remove.... while these properties are not unqiue for alot of liquid liners, something about this shade of brown works (not too harsh yet obvious enough) for daily office wear. 8 hrs later and it's still on my oily lids, with no primer used. Stila had a similar shade of brown but it was pricier and most definitely didn't have staying power. $19.90 from Watsons.
