This set of 12 Duotip pens contains a perfect basic selection of colours for making all kinds of drawings and illustrations. Ecoline Duotip pens contain concentrated, transparent watercolour ink. These brilliant colours, combined with the two different nibs – a narrow bullet nib and a wider chisel nib – give you the freedom to create fine or broad lines and to colour larger areas. The dye-based Duotips work perfectly in combination with Ecoline Brush Pens and Ecoline bottles, offering you a wide range of options in line thickness, styles, and colour variations. This makes the Duotip extremely suitable for drawings and illustrations with large colour blocks, as well as for line work and small details.
