The Montblanc Noblesse Oblige Navy Blue is a classic pen that Montblanc discontinued a long, long time ago.
This pen version has an extremely elegant design with a slimmer and longer pen shape compared to current versions such as Meisterstuck or PIX.
The material is traditional resin with dark navy blue color, combined with gold-plated metal details, evoking the classic quality that this pen version is keeping.
