These are the best synthetic flat brushes I have ever used. They are great for applying paint for underpainting, blending and glazing. If you take good care of them they will last a long time. They have a very crisp chisel edge that is wonderful for painting tight realism with clean edges. Set of 7 brushes, 1 each of sizes 2, 4, 6, 8, 10, 12 and 20 This is the complete set of synthetic flat brushes and includes all of the brushes in Small and Medium sets, and the Size 20.
