First fountain pens were hard rubber [[safety]], slim and straight form, in two sizes distinguished by the inscription ''"Haro"'' 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]].
