The M.A.C. 182 kabuki brush.
My favorite brush.  Not only could i go on for days about how soft and full the brush feels on your face, but the quality and versatility of this brush is amazing.  Need to put on a tinted moisturizer?  Need to set your liquid foundation with powder?  Apply a powder with coverage with no foundation?  This brush does the trick.  
Warning:  It is so soft, i often find myself swirling it on my face for much longer than needed.  Which blends out my product too much and i need to use more, which wastes in the long run.  Keep track of yourself while using it.
