The Golden Polyamide Fibers used in the fabrication of these brushes are absorbent and durable. They do not have the same capacity for holding colour as natural fibers but they are more resitant. Their flexibility makes them perfect to apply liquified colors. These brushes have stainless steel ferules and wooden handles. This set includes 8 flat brushes: No. 0, 2, 4, 10, 12, 18.
