The dark purple with glitter particles of Max Factor X-Pert eyeliner is a great, intense and opaque color. Although I am untrained in dealing with eyeliners, I succeeded with the long, thin and flexible tip right away, him both very fine, and apply a little wider. He takes a moment until it is dried and then is waterproof. My fine eyeliner has survived even a few hours of sleep, without being smeared. He is sometimes a shampoo in the shower, if I do not rub too hard my eyes. Still, he can be removed with my facial cleansing well. It should be noted that he quickly begins to crumble when applying it too thick.
Easy to use, great color, high stability - highly recommended!
