Montblanc 320 is a vintage fountain pen from Montblanc’s slim-line series, produced in the 1960s–1970s as a refined, everyday writing instrument positioned below the Meisterstück line. It features a clean, understated design with a lightweight resin body and gold-plated trim, paired with a smooth gold plated nib that offers a reliable and comfortable writing experience. The 320 is valued for its balance, practicality, and classic Montblanc craftsmanship, making it an appealing choice for both collectors and daily users. The pen is in very good condition and has been carefully cleaned. Shows very light signs of use consistent with age, including micro-scratches and small marks visible under certain angles.
