Wooster Brush A1147 1-1/2 Solvent-Proof Chip Brush
I like buying disposable brushes in quantity, as it ends up being cheaper that way. This package, from Wooster Brush, gives you 24 disposable brushes; enough to last for a while. While this particular package is for 1-1/2-inch brushes, they have the same thing for 2-inch, 2-1/2-inch and 3-inch. Wooster is one of the largest manufacturers of paint brushes, taking a close second after Purdy for providing top-quality brushes. These are white china bristle, so they are compatible with all paints. They are stiffer than many of the synthetic brushes, so they can also be used for glue and other higher viscosity materials.
