{"product_id":"series-7-watercolor-brush-round-4","title":"Series 7 Watercolor Brush, Round, #4","description":"Refine your watercolor techniques with the Series 7 Watercolor Brush, Round, Size 4 by Winsor \u0026amp; 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.\n\nThe 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.\n\nThe Winsor \u0026amp; Newton Series 7 remains the gold standard for artists seeking heritage craftsmanship and unparalleled performance.","brand":"Winsor \u0026 Newton","offers":[{"title":"Default Title","offer_id":43701312487498,"sku":"WNX5007004","price":68.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0582\/1146\/7338\/files\/309634518.jpg?v=1781405293","url":"https:\/\/checkout.inspire.world\/products\/series-7-watercolor-brush-round-4","provider":"Inspire World","version":"1.0","type":"link"}
