probably out of all the brushes I use, my favorite is the "White Angled liner Brush" from coastal scents.
I like my EDM/CS brushes for my foundation, face, shadows...but that might just be because those are the only ones I own and have used. But the angled liner brush is soo cool...it's amazing how one slight little bend can make it so much easier to actually *see* when you're lining your eyes! (the bend makes it so the brush handle is actually to the side of your eye sight when you're lining your eyes, instead of directly in front of your eye, blocking your vision)
