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 we measure a brushA visual guide to the measurements shown in the size chart above.
These are the same measurements shown in the size chart above. Brush sizes are not standardised across brands, so use these dimensions when comparing brushes within a series or between manufacturers.
Tuft Length
The visible length of the brush hairs, measured from the ferrule to the tip.
Belly Diameter
The widest point of the brush head. On round brushes, this is the widest part of the belly.
Total Length
The full measurement from the tip of the brush to the end of the handle.
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.
