This brush cost 15 bucks
It's small enough to use for contouring of your nose, pad loose powder on your under eye after applying concealer, dusting highlight on your cupid's bow. These are just some of the stuff I use it for. I'm sure there's other purposes for this brush as well.
I like that this brush is soft like any other brushes by Real Techniques. It's synthetic and doesn't require long drying time.
