The release of these brushes represented a major breakthrough in brush making. Pro Arte's Prolene range of superb synthetic watercolour brushes are renowned for outperforming many sable brushes, lasting longer and being more affordable. The brushes are also popular for meeting the concerns of those who were troubled by the use of animal hair. Used mainly for watercolour these brushes have incredibly soft fibres, which feel closer than ever to natural sable, but with all the durability of a synthetic brush.
The Prolene Spotter Brush has been designed to allow the artist to make small, minute strokes and spots.
