These are so pretty. I got one for free when I was trained but I prefer to use stick eyeliners. Lisa Eldridge, one of my favorite makeup artists, raves about these because of the diverse color options.
This pencil is SO soft. I like to use the Laura Mercier Caviar Sticks for everyday, but this one is much blacker than the caviar stick and is better for an evening look. It smudges a little so I love it for a smokey look.
