Etoile de Montblanc Collection. A Jewel that Happens to Write! This elegant new signature collection is Montblanc’s first core collection to feature the patented star-cut Montblanc Diamond in the cap. Black resin barrels with platinum-plated fittings feature a uniquely designed clip, reminiscent of a woman's arm. Each fountain pen features a rhodium plated 18kt gold nib, available in M, F and XF, and fills via a cartridge only. A Premium model is also available which features pave round diamonds in the upper and lower end of the clip and a larger patented star-cut Montblanc Diamond in the cap.
