"Love how fine this pencil is! Great for natural brow looks"
— Angie B. (5/5)
"The perfect size to define brows. New favorite!"
— Tiffany J. (5/5)
"This is a lovely formula and the medium brown is perfect (usually a soft brown in Anastasia). My only complaint is just that it's sooo skinny and the pencil isn't very long so I feel like I will have to be refilling soon. I wanted the angled pencil that is slightly bigger but it was sold out!"
— Samantha M. (4/5)
"shoulda bought bigger tip but still nice"
— Sb T. (4/5)
"great detail and looks natural."
— Heidi H. (5/5)
"Best, subtle eye pencil"
— Ashleys S. (5/5)
"This detailing pencil is even better than I could have imagined. I didn't really think it would be much different than previous iterations of brow pencils, but the fine tip allows you to really shape brows and I can't live without it now!"
— Emily I. (5/5)
"Love how fine this is, and yet it doesn't break when applying. It's by far my favorite brow pencil."
— Lucy (5/5)
"this has the best color match and I lie that it’s ultra-fine - more so than other brands. I’m taking off a star because there is such little product in it and it runs out quickly"
— Chava V. (4/5)
"The tip of this is so fine and makes my brows look natural, not like they’ve been drawn on with crayon"
— Brenna L. (5/5)
