The Montblanc Meisterstück Classique (also known as the 145) is a luxury fountain pen defined by its slim profile, handcrafted 14K gold nib, and signature black precious resin. First introduced in 1924, this design icon features a screw-on cap topped with the iconic white Montblanc emblem and uses a versatile piston converter system for both bottled ink and cartridges.
