Finally. Where has this brush been all my life?
I have the E25 that came as a free gift with purchase on Sigma’s website so it is shorter and has a different colored handle than the rest of their collection. My E40 is ideal for buffing on a crease shade, but this brush is exactly what you need for adding in more dramatic and defined colors to the crease and outer corner of your eye.
I had previously been using the bigger end of the brush included in my Urban Decay Naked 2 palette to get sharper and more intense color payoff in my crease. That brush is perfectly round and works very well so I was concerned that the flatter shape of the E25 would make applying color evenly more difficult. Quite the opposite. The more pointed shape is conducive to getting color in just the right area of the corner of your lid. Not having a round shape means that you can apply a cut crease look by turing the bristles 90 degrees to the thinner side.
The E25 is multipurpose and my new favorite brush of all time.
