Royal Talens Ecoline Duo Tip Pen

A firm favourite among artists and calligraphers alike, Ecoline is a fantastic transparent liquid watercolour ink which offers a wide range of colours, available in bottled ink or brush pen form. With a shorter drying time than other watercolours we've tested and beautifully bright and vivid colours available in a vast range, Ecoline stand out as some of the best watercolours around.

The 'pure formula' ink, which Ecoline advise is based on dyes and Gum Arabic, is the secret to their fantastically intense colours. The ink lends itself to blending and mixing extremely well - simply add water to the colour laid down by the pens to mix and blend, or, use the handy blender pen.

This pen comes with a broad chisel tip on one side giving you the freedom to make fine or broad lines and to colour in large areas and a fine bullet nib on the other side.

Available in a range of colours.
