The Bare Escentuals double ended precision brush is by far my favorite brush in my entire collection. The smaller, tapered brush is perfect for lining the top lid with darker shadow to create a sexy smoky look, or use it with a lighter shadow to highlight the corners of your eyes or underneath your lower lash line. The wider brush is the perfect size to fill in the whole eyelid in a way that looks soft, sexy, and natural without caking makeup on. If you have had trouble mastering the smoky eye before, try it with this brush! I have also used this brush after gently wetting the end and then dipping in powder and it makes a perfect, thick, liner. Simply tap the brush gently and carefully clean it to restore it to its dry state. I use this brush every single day and it hasn't shown any signs of breaking down or wearing out yet.
