I have the CC 20mm gold pin brush, I think it works great and have no complaints about it. when I was window shopping for a good brush it made my head spin there are so many choices.
I just recently orders the Madan brush for a gift, I obviously haven't tried it out but the package comes with a hole that allows you to feel the pins. I am most likely going to buy one for myself just from the feel of it, can I want a pink brush.
