I just bought the ones in the package above this morning at the store in Cedar Rapids, IA.
I'm sure other brushes will work as long as they are synthetic brushes with short bristles, and stiff.
The clear plastic-handled blue ones in this picture are this brand:
Loew-Cornell - 223 Shader, 225 Stencil, 228 Scrubber
Smallest blue wood-handled one:
Loew-Cornell - 690 Fab Spotter
The green one is ArtMinds 3 (Same brand as ones in the package).
Other brushes from Michaels
