Discovering the Right S.T. Dupont Pen for You
S.T. Dupont produces a variety of fine writing instruments, categorized mainly into:
-
Ballpoint Pens
-
Rollerball Pens
-
Fountain Pens
-
Mechanical Pencils
Each writing tool requires a specific type of refill—they are not interchangeable.
Ballpoint Pen Refills
S.T. Dupont ballpoint pens use oil-based ink refills that are ideal for smooth, everyday writing. These refills are available in classic colors like black, blue, red, and green, and come with fine or medium tips.
Compatible with popular models such as Line D, D-Initial, Liberté, and Défi.
Pro Tip from Marini: Medium black is the most versatile choice for daily writing.
Rollerball Pen Refills
Rollerball pens combine the elegance of a fountain pen with the practicality of a modern ballpoint. Their water-based inkprovides a smooth, fluid writing experience—perfect for signatures and detailed notes.
⚠️ Important: Rollerball refills are not compatible with ballpoint pens, even if they appear similar.

-
Proprietary ink cartridges, which are slightly longer than standard international sizes
