The real turning point in the [[OMAS]] production happened in 1932, when it introduced what is was for several decades one of the top models of the company, the [[Omas Extra]], made of faceted celluloid, a [[lever filler]] model with a very large cap band, decorated with a greek pattern. The pen was produced in four different sizes and launched with the slogan ''the creation of an artist and a scientist'', and it was accompanied by a very extensive advertising campaign.
