It's very easy to apply, last long it doesn't come off easily, it's very smooth when applying, gives a lovely touch to the eyes,the glittering its not to strong it is perfect, nº3 it's perfect for the teardrop line or the bottom line, if you have brown eyes the #2 brown eyeliner will accentuate the brown color of you eyes (it surprised me, because i have dark brown eyes and i don't pay much attention to my eye color since is a regular color in the place i live, but after using the brown color, i've forgotten the black eye liner, i began to love the color of my eyes), #1 it's lovely with some glittering touch to a black eyeliner it's wonderful how it change the look. They can be used has eyeliner or eyeshadow, if you want to use it has an eyeshadow the line must be thicker and you have to be fast spreading it. I like it more has only an eyeliner.
