Sorry, that's compared to my £3.50 Wilkinson Sword boar hair brush, and also my old Simpsons Duke2 which was about 1/4 the size of the B&B brush. Compared to either of those it's a monster.
I made a point of lathering on my face with it this morning, it does work though I think it works better lathering in a bowl. I need to do more research and testing. :hmmm:
