The case described is a counterfeit; the deviating logo is an unambiguous recognition feature; original cases typically show a clamping for holding the fountain pen. For reversal, the path via PayPal buyer protection is recommended, since the effort is small. With proven counterfeit, the fake status can be confirmed by Montblanc and, if applicable, a complaint filed, since the sale of counterfeits in Germany is punishable. Buyers should carefully check cases before payment, since counterfeiters often make obvious errors on the logo.
