Translations:Zerollo/9/en

The company had some success, and was able to sell its products abroad relying on Dunhill for the English market and on Unic for the French one. But although functional it was still a pen equipped with a very complex and delicate mechanical system, difficult to repair, which made it brittle and all in all not much more convenient to use than the simple and straightforward solution to carry around two pens. While maintaining production based only on this particular model, and not being able to produce further innovation, with the fall of the interest aroused in the initial period, Zerollo suffered a progressive decline disappearing from the market after the Second World War.
