Winsor & Newton's Cotman watercolor brushses are a range of synthetic brushes made by blending fibers of different thicknesses to achieve the most important qualities sought after by the watercolorist — strength, spring, and color holding capacity.
Series 888 fan brushes have nickel-plated ferrules and short blue lacquered handles.
Note — Brush sizes are not standardized. The length and width of a brush of a given shape and size varies considerably by manufacturer. Since fine art brushes are handmade, expect some variation even among brushes from a given manufacturer.
