I got this as a gift from my sister this past Christmas. It's the Sigma F86 Tapered Kabuki Brush. It's a little pricey but it's worth every penny!
If you're a liquid foundation kind of girl (or boy) I recommend this brush! Because of the tapered end, it is very precise with the blending. But I don't wear liquid foundation, I personally use this brush for my liquid under eye concealer. Seriously, I am in love with this brush. It works absolute wonders and I don't see myself using any other brush for my concealer.
