Its one of the many brushes from the Wayne Goss brush Collection.

I bought it to use it just as a highlighter brush but I realized it’s just as amazing for applying blush, and to contour with. Also you can just use it as a regular powder brush. I am going to be ordering a few more because yes I really do like it that much. Plus the hairs are so soft it feels amazing on your face. Apply highlighter and blush beautifully.
