My absolute favourite brush by far. It's extremely dense and fluffy and feels very soft and luxurious on the face. Great for applying powder all around in a quick manner.
Don't be fooled by the in-store display brush since it has been roughly touched by many people so it will look fluffier.
In comparison to other big powder brushes from other brands, the Sephora collection one is just as high quality without breaking the bank. Though it's still expensive for just one brush, it's very worth it and as long as you take care of it, it will last a very long time.
I like to keep the little plastic packaging that holds the bristles in place so that the brush holds its shape overtime, and also to protect it when I take it with me travelling.
