Thanks everyone for entering my Sigma giveaway, the contest is now closed. A brush that I really enjoy from Sigma that doesn't get much hype is the E45, the Small Tapered Blending Brush. It's great for putting colour in the crease and blending it. This brush is very similar to the MAC 226 brush, which was a limited edition brush from the Blond Brunette Redhead collection. If you missed that collection and are craving a brush like that, this is a great one to pick up, it's only $9.
I bought this brush back in the summer, here is the original post and also notice how the shape has significantly changed over time. The second picture was taken when I received it and the top is now. Although I don't mind the change, I wish it had stayed pointy like that. I think if you keep your brushes in a brush guard, tightly condensed, you can keep that shape, otherwise they do tend to fluff out naturally.
What's your favourite eye brush? Do you use the E45?
