Synthetic watercolour range covering rounds, flats, riggers, and more. Reliable and affordable.
The Winsor & Newton Cotman range is the brand's synthetic watercolour brush line, named after the landscape painter John Sell Cotman. It covers a comprehensive range of shapes — rounds, flats, riggers, filberts, mops, and more — all using W&N's synthetic fibres designed to mimic natural hair performance.
Cotman brushes are the go-to recommendation for watercolour beginners and students, offering reliable point retention, decent paint capacity, and consistent quality across the range. They are also practical for experienced painters as utility brushes for masking fluid, mixing, and techniques that would risk expensive sable. The short-handle format is standard across the range.

How to care for your brush
Rinse after each session. Cotman synthetics are durable and forgiving. Clean with brush soap as needed. Reshape and store normally. These brushes tolerate more casual handling than natural hair but last longest with proper care.
