I'm currently using real techniques brushes and I HATE the crease brush. WHY is it SO BIG? I like their detail brush though, because I can define my crease really well and then blend. I love that. But that crease brush is just terrible--if you have small lid space like I do
The foundation brush (for powder) is ok.
Are the duo fibre brushes from Crown actually duo fibre or just different colours of fibres?
