The brushes have Pur Minerals and the type of brush (i.e., Powder, Utility, etc.) on them.

Brushes should be cleaned regularly because the oils from your skin can accumulate on the brush and interfere with proper application. Once a week is best. Those with oily skin will need to cleanse brushes more often. You can adjust how often depending on your skin type. We now offer a professional-grade brush cleanser, Sweep It Off, that is a quick-drying spray to make cleaning brushes easier.

Our brushes are made from cruelty-free goat, sable, and pony hair. The only exceptions are the Maximum Coverage Brush and the Brow Brush which are synthetic.

The zippered bag has slots for each of the brushes. It also has a few extra slots for any other brushes you may want to carry. There is even a slot large enough for our Chisel Brush.

The Chisel Brush is sold separately. This brush set contains full-sized brushes. The brushes included are our Powder Brush, Utility Brush, Blush Brush, Shadow Brush, and Lip Brush.

The Pür-fect Makeup Brush Collection is made in China.

The Utility Brush is specifically designed for small areas needing superior coverage, like dark circles, broken capillaries and blemishes.
