The system, clearly influenced by the ''[[crescent filler]]'' of which it is essentially an alternative, involves the presence of a metal rod that covers about half the diameter of the body of the pen, connected internally to a pressure bar located on the opposite side of the inner rubber tank.

Tirando la barretta (chiamata ''collar'', da cui l'altro nome del sistema) si comprime il serbatoio in gomma e si consente così il caricamento della penna. Come si può facilmente intuire il meccanismo è sostanzialmente analogo al ''[[crescent filler]]'', con il vantaggio di sporgere meno dal fianco della penna, resta comunque non troppo gradevole sul piano estetico.<noinclude>

By pulling the rod (called the ''collar'', from which the other name of the system) you compress the rubber tank and thus allow the filling of the pen. As you can easily guess, the mechanism is substantially similar to the ''[[crescent filler]]'', with the advantage of protruding less from the side of the pen, but still remains not too pleasant on the aesthetic level.<noinclude>
