The mechanism allows to avoid the presence of the blind cap of the [[button filler]], and the related problems of loss, at the cost of a certain mechanical complexity. Its main purpose, apart from distinguishing itself from other manufacturers, however, it is mainly to aesthetically pleasing avoiding a gap on one side of the pen.

Una variante del sistema, introdotta sempre dall'[[Aurora]] con il modello [[Superna]], prevede il montaggio della levetta di fondo in posizione verticale; la levetta viene montata all'interno di una struttura in alluminio inserita sul fondo della penna, che si cura di assorbire gli sforzi. La levetta emerge da una cupola a forma semisferica e può essere azionata tramite una pallina di plastica posta sulla estremità esterna.  In questo caso si accede al meccanismo svitando il fondello e si carica la penna spingendo la leva tramite la pallina.<noinclude>

A variant of the system, also introduced by the [[Aurora]] with the [[Superna]] model, involves the mounting of the bottom lever in a vertical position; the lever is mounted inside an aluminium structure inserted in the bottom of the pen, which takes care to absorb the stresses. The lever emerges from a hemispherical shaped dome and can be operated by means of a plastic ball placed on the external end.  In this case, the mechanism is accessed by unscrewing the bottom blind cap and charging the pen by pushing the lever through the ball.<noinclude>
