Cotman Watercolor Brushes feature a unique blend of differing thickness fibers. The thicker fibers give strength and spring while the thinner fibers improve color carrying capacity. Together they retain a perfect point, time after time. The handles are designed to provide balance and comfort when painting. The ferrules are made from high quality nickel-plated brass which helps to prevent corrosion, clogging of hair and enables easy cleaning. The range features a wide selection of head shapes and sizes to suit all watercolor techniques.
