The multiliner SP are a range of high-quality technical pens from Copic. With waterproof and lightfast pigment ink in replaceable cartridges, separate replaceable nibs and durable brushed aluminium bodies. Ideal for sketching, technical drawing, outlines, manga and much more. The nibs are available in a needle fine tip up to a foam brush for a huge range of line widths. Since the ink is waterproof yet water-based, it will not bleed or smear if used with watercolours or alcohol-based markers.
