This set of 3 Duotip pens in primary colors is a great basic set to start your collection. Easily expand your color palette by adding the set with secondary colors and create a complete color spectrum with just six pens! Ecoline Duotip pens contain concentrated, transparent watercolor paint. These brilliant colors, combined with the two different nibs—a narrow bullet-shaped nib and a wider chisel-shaped nib—give you the freedom to create fine or broad lines and to color 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 color variations. This makes the Duotip ideal for drawings and illustrations with large color blocks, as well as for line work and small details. Contents: 3 pens (205 Lemon Yellow - 337 Magenta - 578 Sky Blue Cyan).
