This set contains 5 Ecoline Brush pens in vivid grey shades. The Brush Pen is characterised by its flexible tip and extensive range of brilliant colours thanks to its pure, dye-based formula. The transparent colours offer the best results when used on white or very light-coloured paper. If you wish, you can easily decrease the colour intensity through thinning with water. These pens are perfect for hand lettering, watercolour drawings, quick sketches and finishing touches.
