The creation of the pen is linked to the activities of the Quadretti store, dating from 1938-39, which specialized in the sale of fountain pens, and the prototype of the pen, still in possession of the heirs, was built around the 1939. At that time it was in vogue the trend of "double" pens (launched by the Zerollo and continued with other models such as the Itala) able to write with two different colors.
