Gently wash the coating surface to remove grease, soap residues, oil, etc. Let it dry. Shake the marker closed with the cap for about 30 seconds. Remove the cap and gently press the tip of the marker onto the paper until the color appears.
Be patient, all the fibers of the tip of the felt-tip pen need to be soaked in paint.
The tip of the felt-tip pen is replaceable. Rough joints can slightly damage (wear) the tip of the marker. Simply take it out, turn it over and put it back in the marker. The coating is dry to the touch after 2 minutes. About 50 long meters of joints with a width of about 5 mm can be covered with one felt-tip pen.
