This set of 3 Duotip pens in secondary colours is a great basic set to start out your collection with. Easily expand your colour palette by adding the primary colour set and create a full spectrum of colours with just six pens! Ecoline Duotip pens contain concentrated, transparent watercolour paint. These brilliant watercolours in combination with the two different nibs, a slim bullet and a broader chisel tip, give you the freedom to make fine or broad lines and to colour larger areas. The dye-based Duotips work perfectly in combination with the Ecoline Brush Pen and Ecoline bottles and offer you a wide range of options in line weights, styles and colour variations. This makes the Duotip extremely well suited for drawings and illustrations with large colour blocks as well as linework and small details.
