Pur Minerals is not exactly the company I would think of for mascara, after all, their focus is on mineral makeup. But I gave a sample of Pur Minerals Mascara a try and it is a pretty darn good basic mascara.
The brush on this one is of standard size. The formulation worked well for me in terms of very nice definition and lengthening, and not so much in terms of volume, which is actually my preference in a mascara. I had no clumping, and the mascara wore well without smudging. It removed just fine with a makeup remover cloth.
Pur advertises this one as particularly contact lens friendly, with no tar or fibers. At $15.50, it is a mid-range price mascara, and its quality fits that price range pretty well.
