In 1933 was introduced the [[Novum]] model in two versions, with smooth or faceted body and cap, produced in a variety of different celluloid colors. The pen had a particular ''[[levetta di fondo|back lever filler]]'' system and a special security clip, present on the larger models, that at the insertion of the pen in the pocket triggered an hook that clipped the outside of the pocket fabric to prevent accidental exit, and that should be released by pulling forward the tip of the clip. With several variations the pen remained on the market until the early 40's. | In 1933 was introduced the [[Novum]] model in two versions, with smooth or faceted body and cap, produced in a variety of different celluloid colors.
