rotring Isograph Technical Drawing Pen

The classic steel-nibbed technical drawing pen, familiar to several generations of draughtsmen. Although now largely superseded by those wretched computer thingies, these pens are still valued by those who think the pen is mightier than the mouse.

The isograph features a refillable ink reservoir, and a patented push-on sleeve gives easy access to the ink helix for cleaning, even when the ink reservoir is full. Line widths for drawing as per ISO 128 and DIN 15, and for lettering per ISO 3098/1 and DIN 6676.
