This brush is incredibly soft and spreads out foundation on the skin evenly in a thin layer without any traces. But  the most amazing thing is that there is almost no residue of the product left on the bristles after that. The brush feels and looks almost completely clean. I have never experienced this with other brushes. And of course the concealer side is also incredible, you don’t need to dirty your fingers any more, the applicator on the other side of the brush does it all for you. It’s expensive though but I purchased it with good discount so I am quite happy.
