Translations:Haro/4/en

First fountain pens were hard rubber safety, slim and straight form, in two sizes distinguished by the inscription "Haro I" or "Haro II" on the barrel. Later production used both lever filler and button filler. In 1937 the Haro, as one of the first companies to jump into the economic production market, gave rise to the publication of a newspaper called "Haro-Winkle". In this period the production shifted to celluloid colored pens (blue, green and black pearl striated) using the piston filler.
