Royal Talens Ecoline Brush Pen
The Ecoline brush pen uses a fantastic transparent liquid watercolour ink. The ink has a shorter drying time than other watercolours and is beautifully vivid. The bright ink lends itself to blending and mixing extremely well, simply add water to the colour to mix and blend. The pens use a large fibre-brush nib which is soft and flexible, perfect for achieving a variety of line widths and effects. These nibs also keep their shape very well. The ink is water-based and not very light-fast, so Ecoline advise keeping your finished work protected in a portfolio for better colour retention.
