🔹 More stable, more reliable – Enhanced formulations for smooth, clog-free flow and optimal performance in all fountain pens.

🔹 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.
