Sorry it took me so long to get this up, I know I received this in January along with the flat top brush. The the 102 Blush Brush is a flat, natural-hair brush with long bristles and a domed top.
This brush as a lot of bounce, which means the bristles are very flexible and soft, which I really love. It picks up colour VERY well with almost no fall-out, and deposits it where I want it. I use this with my Chanel Joues Constraste blush, which is a baked formula and thus usually has fall-out, and this brush “absorbs” all of loose flyaways from the blush.
Overall I strongly recommend! I bought mine from Hautelook, but they also have sales on Beauty Story. R&R cosmetics are being clearanced out, so if you see this in a sale, I recommend grabbing it immediately!
