Translations:Radius/10/en

There is no known date of termination of production under the Radius brand, but it is placed in the second half of the '50s (but certainly later than 1956, appearing SAFIS in this yearbook of that year) considering it concomitant with the cessation of activities of the parent company, which was probably put out of business by the success of ballpoint pens. However, there are no reliable documents or precise indications about the cessation of activities.
