I don't know if it is a camera lens thing but those brushes look big enough you could paint the whole house with them!
Both the Shavemac and the B&B are 23mm knots while the Saville Row is an 18mm knot. The bloom on the B&B is enormous, I enjoy all of them but would not order anything else as big as the first two. They are just a little too big for my face.
