For the few dollars they cost, E.yes L.ips F.ace make up brushes are good. I like their $1 brushes but am now digging their studio collection so if you're feeling shi-shi, you can upgrade to their studio collection of brushes that are a whopping $3 a piece.
I have the studio collection blush brush and their eye shadow brush and I like them both a lot. The studio brushes boast soft, synthetic bristles (which means no animal cruelty going on) and ergonomic handles. Next time I am in Target, I plan to get the powder brush, complexion brush and contour brush from the studio collection.
All of these brushes I've talked about and many of the $1 brushes, I use in my professional make up kit. You read right. I beat clients faces with $1 and $3 brushes! Use what works. Sometimes cheap works, sometimes it doesn't. In this instance, cheap is working for me. :D
Check out this vid below. You can get the whole set of studio brushes for just $30! I plan to get two of these: one for my kit and one for my personal use.
You can get E.L.F. brushes at your nearest Target: http://www.target.com/, if you live in NYC: Jack's 99cent store (only the $1 ones though. They don't carry the studio collection.), or online at http://www.eyeslipsface.com/
