Instead, until this brochure was found, it was unknown the use of the FERT brand, found on pens imprinted as "F.E.R.T. Automatica Brevettata" with the reference to a patent (nº IT-330806) probably referring to the filling system, consisting of a thin U-shaped spring made from an elastic lamina, which can be side pressed to compress the rubber sac, after unscrewing a back blind cap much longer than the usual ones.
