Le Metier de Beaute Powder brush. Soft, and picks up a good amount of powder without getting it all over the place. Handle just the right length too. Why have I ignored this brush for so long???
MAC 179. It is a limited edition, part of the Semi-Precious collection I believe. I actually bought all of those brushes but this one I forgot about. It's actually the only buffer brush I have, and it's really big so it's easy to get a smooth all over powder application. It's really soft for a MAC brush too. I should have been using it sooner, but better late than never!
