Giacomazzi worked mainly in manufacturing for third parties, and branded pens in his name are unknown at least until the '50s. The only brand they definitely own is the [[Olimpica]] for which there is a record in 1944 by Dino Giacomazzi  ({{Marchio|90736}}), other brands with quality production attributed to Giacomazzi are [[Point red]] (which, however, was an Ubaldo Massari of [[Mastilo]] trademark), [[Sirium]] and [[Sirium Extra]].
