After the war OMAS resumed production with a change of style, producing pens with a new ogival shape, and adopting the piston filler. In 1946 the Extra line was completely restyled, the wheel clip was maintained, but were used three ring on the cap as decoration, and the filling system was changed to piston filler, with a transparent section for ink level display. They were produced in three sizes, small, medium and large, identified respectively by the numbers 555, 556 and 557.
