A refill, one might think, is a modest affair. And yet, this particular one has rather higher standards. Designed exclusively for the Pentel Calme single-colour pen, it preserves everything that makes the original so agreeable—smooth writing, quiet confidence, and not a smudge in sight.

The refined oil-based ink produces a consistently dark, crisp line, while its quick-drying nature ensures your notes remain exactly where you intended them—on the page, not your hand. With its ultra-fine 0.35mm tip, it’s especially suited to those who appreciate precision, neatness, and margins that behave themselves.

It’s not interchangeable, mind you. This refill knows exactly where it belongs—and performs all the better for it.

Precision in the Details:

• Exceptionally Fine, Tidy Lines: The 0.35mm tip always delivers precise, controlled writing—ideal for detailed notes and compact handwriting.
• Smooth, Smudge-Resistant Ink: The improved oil-based formula ensures dark, clean lines that dry quickly—no smears, no second passes.
• Made for Calme, and Nothing Else: Designed exclusively for Pentel Calme single-colour pens—never a compromise, always a perfect fit.
