I've been using my Bare Minerals makeup for about two years now, I guess. Along with the minerals themselves I bought three brushes for applying the makeup. The bristles are, apparently, made of goat hair.
The smallest brush is for applying the concealer that goes on first. I use this to cover the little red veins in my cheeks and to help my eyelids and under my eyes to look brighter.
The medium sized brush is for applying blush and is my favorite because it is so soft! This is the one that gets the least amount of use because I only apply a tiny bit of blush.
The large brush is for putting on the overall finishing cover. It doesn't take much, and the large brush just helps it to go on nice and evenly.
I have enjoyed using the Bare Minerals makeup and the brushes are easy to use and work great
