Review (4/5): Cheap and easy to use - Use an eyebrow wax over it for an all day stay!
Surprisingly, I actually liked the product. I use this first to draw outline and fill, than I use my Anastasia's brow pomade to fill in sparse areas and to ensure it stays on all day.
I sweat easily so by itself, it does not last even though I work in an office atmosphere, I do one touchup around lunch time. But with a little pomade or even eyebrow wax it does stay on a lot longer. I went out to a country concert with friends and used the pomade and wax over the pencil, it lasted from 6 PM till 3 AM.
It's super cheap, so a great alternative to try.
