ROTRING ISOGRAPH TECHNICAL PEN 0.5

Description

This technical drawing pen features a precise, chrome-plated tip and an ink reservoir that can be refilled using bottled drawing ink. Ink flow is achieved by gravity (as opposed to the capillary mechanism used in the Rapidograph pens). The Isograph’s large ink capacity and wear-resistant tip make it perfect for heavy use. Its push-on nib sleeve makes cleaning fast and easy. Each pen has a color-coded barrel and labelled screw-on cap.
