Rotring was established in 1928 as Tintenkuli Handels GmbH. The company's first product was the Tintenkuli, a stylographic fountain pen, with a narrow steel tube instead of conventional nib. While stylographic pens were already common in America and in fact pre-dated conventional fountain pens.

The Rotring Isograph Drawing ink cartridges consist of special pigments which float in distilled water. This ensures the ink is fast-drying while not soaking into paper, giving it an erasable quality. They are suitable for use in Rotring Isograph technical drawing pens.
