Van Dieman’s ‘Professional’ is a collection of premium quality fountain pen inks engineered with advanced formulations, exhibiting exceptional lightfastness, permanency and water resistance over and above our standard range of inks, engineered for writers, professionals, and everyday ink enthusiasts who demand reliability, longevity, and effortless performance from their fountain pen inks.

Introducing the first in this series—the Essential Inks—designed for Everyday Carry (EDC) and daily writing. These inks offer a perfect balance between performance and practicality, making them ideal for both work and personal use.

🔹 More stable, more reliable – Enhanced formulations for smooth, clog-free flow and optimal performance in all fountain pens.
🔹 Longer lasting – Superior resistance to fading, ensuring your notes and documents stay vibrant over time.
🔹 More water-resistant – While not fully waterproof, these inks can withstand accidental spills better than standard inks.
🔹 More lightfast – Designed to hold up against time and exposure without significant color shifting.
🔹 Safer for everyday use – Unlike permanent inks, the Essential series won’t stain feeds or damage delicate vintage pens, making them a trustworthy choice for your favorite writers.
🔹 Lower surface tension (34-37 mN/m) – Provides better flow, even in fine and medium nibs, for a smooth and consistent writing experience.
🔹 Balanced pH of 7.1-7.5 – Slightly alkaline to help prevent corrosion of metal parts in fountain pens.
🔹 Enhanced anti-clogging properties – Keeps feeds clean and ensures easy maintenance, making flushing and switching inks effortless.
