At least in the early years is also known an economic production under the brands ''[[Eridano]]'' and ''[[Eridania]]'', usually accompanied by a model number, and sometimes by the letters ''PCT'', as an acronym of ''Pecco and C., Turin''. The initial production were eyedropper or safety hard rubber pens, in four different sizes. The same mark was used on a later production for celluloid button filler models. It is also believed that the company has produced parts and pen for other brands, and some believe that also the brand ''[[Scriba]]'' is attributable to [[Stilus]].
