Rollerball Pen Refills – Fluid, Precise, Effortless

A quality rollerball pen refill transforms every word into a smooth, flowing experience. Unlike ballpoint ink, rollerball ink is water-based, which allows for a writing sensation closer to that of a fountain pen—rich, precise, and effortlessly fluid. That’s why choosing the right refill is essential to keep your rollerball pen performing at its best.

At InexPens, we offer a carefully curated selection of rollerball pen refills for a wide range of brands. Not all rollerball refills are interchangeable—some pens require proprietary refills, while others accept standard formats compatible across multiple brands.

• Standard Rollerball Refills – A popular format used by brands such as Schmidt, Diplomat, Faber-Castell, and Pelikan. These refills provide excellent ink capacity and a consistently smooth line.
• Proprietary Refills – Many brands design rollerball refills tailored to their own pens. Montblanc, Parker, and Lamy each have unique refill types, engineered for perfect fit and performance in their pens.

To make your choice easy, we’ve organized our rollerball refills by brand and compatibility. Simply select your pen’s brand and explore the available options. Each product page includes detailed specifications—dimensions, tip size, ink color, and more—so you can compare and be confident you’re choosing the right refill.

Whether you use a Parker, Waterman, Montblanc, Sheaffer, Cross, Lamy, Kaweco, or another leading brand, you’ll find the perfect rollerball pen refill in our collection.

Whether you’re replacing an empty cartridge or bringing a beloved rollerball pen back to life, you’ll find the perfect refill here.
