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 [[:File:1956-Annuario-General-Industria-Stilografiche-A.jpg|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.
