Super simple and very effective. A set of good black pens is an absolute must for any artist. Here you will find an overview of black pens in different thicknesses.
We also recommend the bright coloured Ecoline pens from Royal Talens. These beautiful coloured pens can be used to draw thin precise lines or to colour large areas. These pens work best on Liquid water color paper.
