The Copic Multliner is an exceptional fine line drawing pen that has been specifically developed for use by graphic artists & designers, architects & industrial designers. Its pigment ink is waterproof and very lightfast. The high quality fibre tip is encased in a metal sleeve for added strength and protection. It is ideal for sketching and a line drawn with a Copic Multiliner will stay sharp without bleeding if overdrawn with a Copic Marker.
