Winsor & Newton Promarkers are designed for professionals in graphic design and illustration. Their alcohol-based inks produce clean, even flat areas without brushstroke marks or tonal variation, making them particularly well suited to technical renderings, mock-ups and presentations where consistency of coverage matters as much as colour. The dual tip, combining a chisel nib for broad areas and a fine nib for detail work, covers a wide range of needs without switching tools. Colours are formulated to remain stable over time and resist fading, which is important for work intended to be reproduced or archived.
