For dependable performance and understated elegance, traditional dye-based inks remain the gold standard. Brands such as Waterman and Parker have long been trusted for their smooth flow and consistent behaviour across a wide range of nib sizes.

These inks are ideal for daily writing, journalling, and professional settings. They clean easily, are gentle on fountain pens, and provide reliable colour without clogging when paired with quality paper. If you value simplicity and performance, a classic blue or blue-black will never disappoint.

For writers who enjoy personality and depth on the page, more saturated inks offer a wonderfully expressive experience. Diamine , for example, is beloved for its extraordinary range of shades — from deep oxblood reds to eye-catching shimmering teals.

These inks often provide beautiful shading and character, particularly in broader nibs. They allow you to match your writing to your mood, whether you are composing letters, enjoying some creative drawings or simply want to have a bit of fun with your writing.

With your ink choice it’s not just about the colour but you can also add a touch of sparkle to your work with the large range of shimmer inks. For example Endless Alchemy Obsidian Sun which takes gold glitter to another level. If you want the feel of celestial on your paper these inks provide a whole galaxy of opportunities.

For those seeking something truly special, Japanese-inspired inks such as Pilot Iroshizuku are celebrated for their exceptional smoothness and nuanced colour palettes.

Inspired by natural landscapes, these inks glide effortlessly across the page and frequently enhance line variation. While positioned at a higher price point, many fountain pen enthusiasts consider them a worthwhile indulgence — a small luxury that elevates the everyday.

If permanence is essential — perhaps for signing documents or preserving important records — pigment-based or iron gall inks may be the right choice.

These formulations are designed for water resistance and longevity. However, they do require more attentive pen care, as their composition can be less forgiving if left unused. Regular cleaning ensures your pen continues to perform at its best.

A classic example is Diamine Registrar's Ink, a traditional iron gall ink long used for official records and archival writing.

You can have so much fun with these top inks for your fountain pen. Whether you want to jazz up your letter to a friend, use it every day or enjoy it as part of a creative drawing experience there are so many to choose from that can lift your work and take it to the next level.
