Our take on the Rotring Isograph Technical Drawing Pen, 0.50 mm

The Rotring Isograph is a refillable technical drawing pen with a 0.50 mm tubular nib and a chrome-plated barrel. It is built for precise line work on drafting film and paper, and it takes Rotring Isograph ink cartridges or bottled ink via a converter. At $12.70 at eBay as of November 5, 2026, it sits at the low end of what this pen usually sells for, well under the $25 to $35 it often lists at.
