OMAS manufactured a variety of pens, the top line being the faceted Arte Italiana range, as well as a variety of limited edition pens. In their history, they introduced a number of cutting edge designs including the “Doctor’s pen” which had a tiny built-in clinical thermometer and the double-nibbed Itala in the 20s and the 361 model in the late 40s whose nib could be used as a hard writer if handled in one position and as a flexible writer in another. Their last major design innovation was the 360, a fountain pen with a triangular body to maximize grip and writing comfort, launched in 1996.
