Founded in 1928 with the development of the first fountain pen without a conventional nib, the "Tiku" or "Inkograph", rOtring came to dominate the market for technical drawing pens and accessories with the Isograph and Rapidograph pens and the huge range of associated drawing instruments. The market for traditional drafting pens collapsed with advent of computer-aided design, but the Isograph and Rapidograph are still going strong, and are much-loved drawing tools. Recently rOtring has reintroduced old favourites such as the rOtring 600 pencil; and updated items such as the rOtring Xonox into the Tikky range.
