In [[1937]] the [[Superna]] model was introduced, with a variation of [[levetta di fondo|back lever filler]], in which the lever was equipped with a small ball on the outer extremity and mounted vertically in a semi-spheric alluminium structure located on the bottom of the pen. The ink loading was carried out by removing the back cover to access the the lever and operating it through the ball.

In [[1938]], following the  ''visualated pens'' trend  showing the ink level started by the [[Vacumatic]], [[Aurora]] introduced the [[Optima]] model, a [[plunger filler]] made of transparent celluloid, which remained in production until the early '40s. Another model of the same year was the [[Topolino]], a simple [[button filler]] entitled to the Disney character, featuring a Mickey Mouse engraving, and oriented to youth people and students, soon paired with [[Biancaneve]]. From the same period should be noted the [[Iridia]] model and the [[Aurora ML|ML]] line introduced in [[1938]], produced, at least officially, for the armed forces officers.
