For over 150 years, the brush makers at Winsor & Newton have applied their knowledge to produce brushes of the highest standard. As new materials have become available they have used their 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. The secret of the Cotman brush lies in the fibres. By blending fibres of differing thickness Winsor & Newton achieve the three most important qualities sought after by the artist. The thicker fibres contribute strength and spring whilst the thinner fibres improve colour carrying capacity. Together they retain a perfect point, time after time. The Cotman Series 668 Filbert brush has a flat shape with an oval tip best for use with water colour for broad marks with a soft edge. It combines the control of a One Stroke brush with the softer edges of a round. All Filbert brushes come with golden synthetic tip dyed filaments, attached by nickel plated seamless ferrules to metallic blue gloss wooden short handles. Available in sizes: 1/8”, 1/4”, 3/8”, 1/2”, 3/4” & 1”
