Pro Arte's flagship synthetic — a fine polyester that mimics sable for watercolour. Springy, fine-pointed, made in England.
Pro Arte Prolene is the maker's long-standing flagship synthetic watercolour range — a fine polyester filament engineered to mimic natural sable. It has been a benchmark artist-grade synthetic for over thirty years, valued for a fine point, good spring and smooth colour flow at a fraction of sable's cost.
Prolene sits above student ranges such as Pro Arte's own Masterstroke: a professional-leaning synthetic for watercolourists who want sable-like handling without natural hair.

How to care for your brush
Rinse after use and clean with brush soap periodically. Prolene holds its point well; reshape after washing and dry flat or tip-up. Avoid harsh solvents and leaving it standing in water.
