I use the Coastal Scents Italian Badger Buffer Brush Large to apply setting powder. The head of the brush is short and dense; therefore, it buffs mineral foundation into the skin very well.
However, the bristles of the Italian Badger Buffer brush are a little scratchy and sheds like crazy during the first wash. It now sheds a little bit from time to time.
The handle of the brush says "IB103 Flat Bronzer." The total length of the brush is 6 inches. It costs $11.95 on their online store.
Update: Coastal Scents discontinued this brush, but you can still buy it from Crown Brush for $10.95. It's called the Italian Badger Series IB103 Flat Bronzer Brush.
What do you think about this brush?
