The Bobbo-Mack makes scrolling easier and faster because of it's shorter bristles and fine blue squirrel & black synthetic hair. It also pinstripes short lines, 2-4 feet in length without having to change brushes. Plus it will let you letter your signature very small and also do small script lettering. This brush has adequate snap and flexibility other brushes don't have. This allows the pinstriper/scroller to use one brush for four purposes without having to change brushes or color.
