5234 GOLD EDGE 1 1/2" THIN ANGLE SASH | Gold Edge paint brushes are made with an exclusive formula of chemically tipped (CT ) polyester. This filament is very soft and fine to virtually eliminate brushmarks, yet it has added stiffness to push paint farther on the surface and provide control for sharp, single-pass cuts. Excellent for all paints and enamels, Gold Edge brushes offer semi-professional results at a great price.
