Translations:CISEA/2/en

There are similarities between the celluloid used for pens branded CISEA and some Olo and ASCO models, which has given rise to the possibility of some connection with the Aurora, but only for the low-end production, an hypothesis supported by the presence of fountain pen marked Amica Cisea, with the Amica trademark, believed to have been used by Aurora for the production of advertising pens, because of the identity of the finish and metal detailing found on these pens with those of Olo.
