I love Crown Brushes. I think they're super quality and fabulous prices.
I own a few already, mainly eyeshadow ones. So i chose two face ones for my next purchases.
These are from the badger series (my fave!). They are soft, lightweight and small enough for a medium make up bag.
I would definately choose 4 of these brushes over 1 mac brush. I think these were around £5 each. Whereas macs can be more than £30 at times.
The flat bronzer is fab for contouring the cheeks and temples. The angle brush i use for highlight, as its smaller than your average blusher brush, and gets just where you need it to!
