Pro Arte devised this impressive imitation of sable many years ago. Purely synthetic, it looks, feels, points and holds colour almost like sable, yet it is much more durable in use….and abuse! The differences are that the synthetic filament of this paint brush will not rot in the ferrule and the lower cost of this man-made material results in a much less expensive paint brush. All these features make Pro Arte Prolene watercolour brushes an excellent choice for the beginner, but it serves many artists well for serious work in all media. It is identified by a gold tip to the handle and is available in many sizes, shapes and lengths.
