Translations:Radius/5/en

The Radius initial production was divided in two lines: the Superior for the more valuable high-end pens and more valuable, and the Extra for second tier pens sold at lower prices. The Superior line remained in production, with different stylistic and technical changes, including the implementation of Trasparente version, until the '50s, while the Extra line was decommissioned in the late '40s, replaced by other economic production, such as the Comet and the Radius 31, hooded nib models of much lower quality than its predecessors.
