The production sees as its most important brand in the '30s the [[Red Circle]], registered in 1934, which was promoted with an extensive advertising campaign. This was followed by a great variety of other brands, such as [[Regale]], [[Stilnova]], [[Condor]]. The lower end was marked instead ''[[Vereletta]]'' (or even ''[[Verelite]]'' or ''[[Verelyte]]''), while under the [[Plevonia]] brand name were produced some high-end pens. Unfortunately there are no reliable data about the production between the years '30s and '40s.
