This dual-sided marker has a 0.8mm fine tip for fine detailed work and a highly saturated flexible bristle brush tip for larger applications. Art & Graphic Twin is a water-based dye and is most suitable for paper. Because of Art & Graphic Twins water-based dye formula, mixing and blending of colors is an ease. Use the colorless blender for detail work or for adding texture. Pair with BrusH2o for a more saturation to achieve a watercolor effect.
