Copic Multiliner Markers contain fine nibs, allowing you to mark in precise detail. They contain pigment based ink to deliver ultra vibrant colours in your work, which is waterproof, copy safe, acid-free and fade resistant. The colours match other colours from the Copic range so you can use these markers to create fine details in your mixed media artworks. Each marker has a 0.3 mm nib, for precise markings. You can use them on papers and cards in fine art, technical drawing, design and more. The ink is pigment based for vibrant results. The lines won't bleed so you can draw over them with other Copic Markers. This marker contains cool gray coloured ink.
