The Rapidograph Technical Pens features a steel nib suitable for precise, uninterrupted line work and also a white plastic barrel with a refillable ink reservoir. Made of impact and chemical-resistant components for universal use with drawing and specialty inks, each nib size has a color coded cap for nib selection. The double-seal cap is air-tight to keep the nib from drying out and comes with a pocket clip. Made in the USA.
Clean the nibs with the Rapido-Eze Pen Cleaning Kit. To ensure proper and long time use, see this PDF: Rapidograph Pen Care Guide.
