This review is about the Pencil Brush SS219, now also known as E30.
This is what the Sigma site says about this brush:
Precise application of color on the crease, outer corner, and upper and lower lash line. Also ideal to smudge out pencil liner. Natural bristles.
I own a different pencil brush, one by Gosh, that I use dayly for applying colours in my inner eye corner. This Sigma brush isn't as pointy as that one, so I don't use it for the inner eye corner.
I use it mainly for applying colour in my crease. It's really precise that way, and especially black, can be applied perfectly, and nicely blended. If I want some darker colours on my outer v, I also use this bursh.
I haven't used it to smudge pencil liners, but I'm sure it will do well.
Still, even with being a bit more fluffy, it works wonders on my crease, and the only negative thing I have to say, is that the hairs are white. For some reason that has kept me from using it for a time, espcially with the darker colours and black I prefer to use it with. Also, I really don't see this ias a pencil brush, it's not nearly as pointy as for example my Gosh brush.
All in all, a brush everyone should have, because it is the best brush I ever used for the crease, and can be used on other parts of the eyes aswell.
It can be bought for 9 dollars at the Sigmastore. It comes in an eyekit with 6 other brushes which costs, for example, 39 euros at Enchantra.
