Inkzall viltpliiats must 6.2mm

Stays sharp longer, does not spread or collapse under pressure. The durable acrylic tip is ideal for rough surfaces such as OSB and concrete. The felt-tip pens do not dry out even if the cap is missing for a few days. Suitable for use on concrete, wood, metal, plywood, OSB boards, and plastic. Can be used for writing on dusty, wet, rusty, and oily surfaces. The ink dries quickly and does not smudge on PVC or metal surfaces. Slim design - convenient to use. Clip for attaching the pen, e.g., to a helmet.
