What Mack Brush says about their product...
Five Speed:
Which is a larger version of the ” SLIM” from the original set. The five speed is basically a #5 script / scroll brush as the slim was basically a #3 or so.
Heavy:
Which is a larger version of the “LIL BIT MORE” … it’s a little longer and fatter so it has a ton of uses… seriously.
One Liner:
This is a completely new brush… it is Amazing for outlining, details, med. to long lines within an illustration.
