This brush is one of my most used, hence I have 2 (with the prospect of making it 3) one in Sigma normal range and another in their copper range.
Why I like this brush, well aside from the fact that the handle is designed in such a way that it sits beautifully in your hand at any angle to allow you total comfort and movement to really work those eyeshadows into place. Coupled with the super fluffy yet compacted head of bristles that in their creamy off white tone look adorable but also allow you to pick just the right amount of shadow up without fall out.
Not one of my Sigma brushes have ever lost a single bristle, the E25 is no exception to the rule and keeps it's shape and fluffy state long after you have washed it multiple times. There is no sign of my original silver barrel E25 loosen its bristles and I have owned and used it, washing it once a week for the last 18 months!
You also get that luxury feel when you use any Sigma brush which I am a sucker for, it is a pleasure to use and gets great results. I use the E25 for highlighting the brow bone, blending out smoky eyes, and for accent shadowing.
I bought this brush after watching Make up guru Jaclyn Hill. Sigma had free international shipping which was excellent. I got a free mini e25 blending brush to go with it which was an added bonus. This brush is amazing. It adds colour to the lid but doesn't leave hard lines. It is also really good for feathering out the hard lines too. Even though it looks too fluffy, it easily gets into the crease of the eye. The brushes are very reasonable in price and the bristles stay intact! I recommend this brush to everyone.
