Winsor & Newton Cotman brushes are a range of pure synthetic water color brushes of the highest quality that have been created using the same skills, For over 150 years our brush makers have applied their knowledge to produce brushes of the highest standard. As new materials have become available we have used our experience to produce new ranges of brushes, each with their own benefits. Cotman brushes were the first complete range of synthetic brushes to be developed by Winsor & Newton.
