Thanks to Ulta's BOGO deal, I finally decided to try Pur Minerals, and I love it! I did not buy the Chisel brush, though; I've been using my BE Kabuki, and I use the sponge for touchups. I was just wondering what other Pur Minerals users use for application - do you use the Chisel brush, the sponge, or other brush? I've heard mixed reviews about the Chisel brush, so I'm not sure I should buy it. But it seems like the flat top would pick up the makeup better. TIA!
