Talens Ecoline Brush Pen Beige 420 is made on the basis of colorants and gum arabic. The colors of Talens Ecoline are unbelievably clear and brilliant. If you want, you can easily reduce the color intensity by diluting with water or by using the Brush Pen blender. Save original workpieces in a drawing folder for optimum color retention. Colors can be mixed or tamed with the special Brush Pen blender. You can also create beautiful blur and color transitions with it. Forgot to replace the cap? A dried-in brush-tip can easily be saved by dampening it with water.
