I have yet to find the perfect eyeliner for my eye but this one is almost there! It creates a very precise wing so this liner is really good for those who like to wing their eyeliner. It also dries fairly quickly, which is a plus for me and it dries matte which is another plus for me! However, if you have really oily lids, I would't recommend this liner so much because it will smudge and end up below your eye. If you don't have oily lids, it will live up to its name and actually last for 10-12 hours!
Other thing about packaging is that I really like how slick it is but after I use the liner for a while, the cap becomes loose and sometimes when I put the liner in my makeup bag, the cap will come off!
