The twin-tipped Winsor & Newton Metallic Markers offers intense, shimmery colour, perfect for adding highlights and texture to your designs. The pigment-based ink used is lightfast enough to provide long-lasting results. It also blends well with water to create further metallic effects. Each pen is twin-tipped, with a broader bullet nib suitable for filling in large areas, and a smaller one for detailed work. Works on wood, card, paper, glass, acetate, plastic, metal, textiles and more. Opaque and shiny pigment-based ink. Fine tip produces approximately 1-2mm line; medium tip approximately 3-4mm, depending on angle and pressure applied. Can be blended with water, even when dried. Acid-free and lightfast. Great for adding sparkling metallic effects to art and craft projects!
