S.T. Dupont Line D Ceramium A.C.T. Black Rollerball Pen, 412684

Crafted from S.T. Dupont’s innovative Ceramium ACT—a lightweight, ultra-durable aluminum-ceramic alloy—this Line D rollerball pen balances strength with understated elegance. The body is finished in a satin black grid pattern, offering both a secure grip and a distinctive architectural look. Polished palladium accents contrast beautifully with the matte body, and the pen is engraved with the S.T. Dupont signature just below the cap. Like all Line D models, it features a precision-engineered click cap and refined proportions that make it ideal for everyday writing or formal presentation.
