Z-10 Eyeshadow Brush ($45.00) is a small, tapered brush that comes to a very fine, pointed tip. Its shape is much like a pencil brush, but it's a little larger and feels a bit more like a tapered crease brush.
Probably my favorite brush of all in a close rank with the other Z series brushes I have. (powder, cheek, large e/s)
They are the very softest brushes when you need it. The only drawback to them ever is that they do not pick up as much product on harder pans but that is easy to work around. Completely spoiled and everything else feels scratchier and coarse now.
