Koh-I-Noor Rapidograph Technical Pens are made of impact and chemical-resistant components for universal use with drawing and specialty inks. Each cap has a pocket clip and an air-tight double-seal liner. They feature long streamlined holders for good balance. Koh-I-Noor Rapidograph pens are available in a variety of line width sizes with either stainless steel points or jewel points.
•The self-polishing stainless steel points are for use on paper and drafting cloth.
•The self-polishing sapphire jewel tips have 30 times longer life than a stainless steel point on drafting film. Jewel points produce more uniform line widths due to superior whetting characteristics. May also be used on paper and cloth. •For replacement points, see also: Koh-I-Noor Rapidograph Points
