S.T. Dupont Défi‑Millenium Ballpoint Pen Fluo Green

Design & Finish: It sports a vibrant neon-green lacquer body (Fluo collection) combined with a matte black finish — giving it a bold, contemporary and energetic look.

Collection & Heritage: Part of the “Défi-Millenium” lineup — a range that combines the classic savoir-faire of the brand with a sporty, modern aesthetic.

Materials & Build: Made of brass, which gives the pen a solid, durable feel even though it remains relatively light.

Mechanism & Ink Refills: It uses a standard ballpoint mechanism, likely a twist-action to extend/retract the tip. It contains the easy flow refill, it just glides on the paper.

Manufacturing & Authenticity: It is made in France under the S.T. Dupont “maison” — ensuring the authenticity and luxury craftsmanship associated with the brand.
