This brush was used to create my makeup look at the Birchbox Soho store, and I was so impressed by how well it blended the shadows in that I had to buy it. It's the perfect length of a brush for holding and properly applying, and the soft bristles are also just the right length to beautifully blend out rough lines and/or apply the subtle base shades when contouring your eyes. This is such an essential brush, yet I feel like I was let in in some secret because there aren't many (any) like it in the market. Great job Birchbox!!!
