Du-All Art & Drafting Supply

Koh-l-Noor Rapidograph pens have been used by artists, architects, designers, engineers and hobbyists for over 30 years to produce precise, consistent ink lines for any application. These refillable pens have a white plastic barrel with a refillable ink reservoir (ink not included), and nibs made from stainless steel. The double-seal cap is airtight, preventing the point from drying out. Each pen is identified by a standard point size or by its line width expressed in millimeters. This technical pen can be used on paper, vellum or tracing paper.
