Even a simple, black imitation-leather case with snap-button fastener and star logo can be an original. Until the repositioning as a luxury manufacturer from 1991, Montblanc produced the entire spectrum from the cheap school fountain pen to the high-quality Meisterstück and correspondingly also simpler accessories. Cases from the 50s therefore often appear "cheap" compared to later leather versions but are nevertheless authentic. A simple visual or material impression does not suffice to rule out originality.
