supersoft, natural finish, dense bristles
I don't think this brush is going to replace all your brushes like they claim but its sure a good one to have if you have problems with your mineral makeup looking chalky or are too heavy handed with minerals. The nylon bristles are super soft and densely packed but yet does not irritate my face like most natural hair brushes do. It's like a compact kabuki brush that can go around corners easily.
It also fits a 5grm jar lid perfectly and applies really natural. Because its so soft on the skin you can go over spots to get more coverage and it would not make your face sore.
Its best to let your moisturizer soak in well (15-30mins depending on type) as it will affect how well the brush glides on your face.
You might want to bring some of your minerals to a Philosophy counter to see how this will work for you.
