These Pro Arte Prolene Plus Synthetic Brushes are the very best-quality brushes in the excellent Prolene collection. Synthetic watercolour brushes, they have incredibly soft fibres which feel closer than ever to natural sable, but with all the durability (not to mention the lower price) of a synthetic brush. They’re a joy to paint with, and they’re beautiful-looking too, with ferrules in gold plate and teak handles. The Series 007 is the round version of the Pro Arte Prolene Plus Synthetic Brush. We sell it in a huge range of sizes to suit all purposes.
