Nothing compares to the sleek appearance of Montblanc’s dynamic, Silver Fibre Guilloche Collection. The cap and barrel is made of .925 Sterling Silver, platinum- plated Sterling Silver cap inlaid with metal-coated woven fiberglass stripes. The fountain pen is enhanced with an 18kt gold nib available in M, F, XF and B. The LeGrand fountain pen is bottle fill and the Classique is cartridge or converter fill.
