I offer a wide selection of brush sets which fit into 2 general categories. Category 1 are brushes of the same hair type and which differ in the brush diameter. I call these Family Sets. An example of this is my Blended Goat hair and Synthetic sets. You can find the family sets by looking under each family of brushes.
The groups below are a combination of some of my best performance brushes which include both natural hair and synthetic brushes. The groupings are my small diameter, medium size diameter and large diameter brushes.
