The Suqqu F is very soft and I love using it to lay pigmented eye shadows on my lid up to crease area. It gives my eye shadows a soft diffused look.
I am sure you can get many decent brushes that can do the same job for a fraction of the price but hey it's Suqqu. I love the black ferrule because it won't show signs of wear after washing unlike my brushes with the metal ferrule. It is a lovely length, just right for me.
