Refine your watercolor techniques with the Series 7 Watercolor Brush, Round, Size 4 by Winsor & Newton, one of the most iconic fine-art brushes ever made. Crafted by hand in the United Kingdom, each Series 7 brush uses only the highest-quality Kolinsky Sable hair, celebrated for its exceptional softness, spring, and superior color-holding capacity. The brush’s elegant pointed round shape delivers unmatched control, making it ideal for artists who demand flawless detailing, fluid washes, and expressive linework. The Size 4 brush features a finely tapered tip with a bristle length of approximately 15 mm and a bristle width of 2.5 mm. Though similar in dimensions to the Size 3, the Size 4 offers a fuller belly, allowing for increased pigment load, smoother wash transitions, and longer, uninterrupted strokes. The seamless nickel-plated ferrule ensures rust-resistant durability, while the polished short handle provides balance and comfort during detailed watercolor, gouache, and ink work. The Winsor & Newton Series 7 remains the gold standard for artists seeking heritage craftsmanship and unparalleled performance.
