Graphik Line Painters are a fine line paint pen that gives immense depth of colour, even on dark backgrounds. Create layers, dribbles and washes with the opaque waterbased ink in 20 strong colours. These cool pens have a 0.5 Japan nib that is robust and delivers a fluid paint line. Warning the ink is permanent once dry. If you do get it on your clothing keep the area wet until you can wash it properly. This box contains all 20 colours.
