MAC 215 Medium Shader Brush ($25.00) is a new, limited edition (I believe, at least) brush designed to be used for shaping and defining the eye with both powder and cream eyeshadows. It has natural bristles. This brush is like a bigger 214, or a stumpy version of the 227. The 215 is wide, dome-shaped brush that’s packed with bristles. For me, it felt a little rough on the eye. It was less rough when I used powder eyeshadows than when I used cream eyeshadows, which seemed to emphasize the pointy, blunt edges of the bristles.
MAC 163 Flat Top Contour Brush ($35.00) is a new and limited edition brush designed to be used with MAC’s Pro Sculpting Creams, but they are noted as a multi-purpose brush, so they can be used however you find it works. The brush is not MAC’s softest face brush, but I wouldn’t describe it as scratchy. I think the blunt edge gives it a harsher feel against the skin, but when I run it back and forth against my face or arm, it feels fine. It’s tightly packed with bristles, making it a very dense brush.
