Carpenter pen for permanent marking in hard to reach places, on almost all materials that are dust free, e.g. metal, stone, glass, wood, plastic
The very long and narrow mouthpiece (20 mm) means that the pen is particularly suitable for use as an assembly aid when dealing with hard-to-reach places, e.g., drill holes when fitting shelves
The round nib has a stroke width of 1 mm
The quick-drying ink is waterproof and smudge-proof
