What is the best brand of fountain pen ink?

There isn’t one universally “best” fountain pen ink brand—the right choice depends on what you value (smoothness, color range, waterproofing, price, shading, etc.). That said, a few brands consistently stand out among fountain pen users.

Top fountain pen ink brands

If I had to pick one:

• Best first bottle: Pilot Iroshizuku (for example, Kon-Peki, Yama-Budo, or Shin-Kai) — it gives a very satisfying writing experience in many pens.
• Best “buy many colors” choice: Diamine — excellent variety without spending much.
• Best everyday office ink: Waterman Serenity Blue or Pilot Iroshizuku Shin-Kai.
• Best waterproof/document ink: Platinum Carbon Black or a dedicated pigment ink such as De Atramentis Document Ink.

A good starter trio would be:

1. Pilot Iroshizuku Kon-Peki — vibrant blue
2. Diamine Oxblood or Writer’s Blood — rich red/burgundy
3. Platinum Carbon Black — permanent black

One caution: avoid using India ink, calligraphy ink, or acrylic ink in fountain pens; they can clog the feed.

If you tell me your pen model (e.g., Lamy Safari, Pilot Metropolitan, TWSBI, etc.) and whether you prefer blue/black/colorful/waterproof, I can narrow it down.

Because "the best" depends heavily on what you value most—price, color variety, safety in vintage pens, waterproofness, or extreme sheen—there isn’t just one single winner. Instead, the fountain pen community widely regards a few powerhouse brands as the absolute best in distinct categories.

The top-tier brands and what they do best include:

If you want to narrow down the choice, tell me:

• What pen and nib size you are using
• What type of paper you usually write on
• Whether you are looking for waterproofness, a specific color, or special effects (sheen/shimmer)

I can recommend the exact brand and color for your setup.

In the fountain pen community, there is no single "best" brand because the ideal ink depends heavily on what you value most—behavior, color variety, waterproofness, or price. However, a few legendary brands consistently rise to the top for different reasons.

The top-tier brands and what they do best include:

• Pilot Iroshizuku (Best Overall / Premium Experience)
  Widely considered the gold standard of fountain pen inks. They feature incredible, wet, well-lubricated flow that makes even a scratchy nib feel like it's gliding on glass. They are remarkably well-behaved, easy to clean out of pens, and feature stunning shading (like Kon-Peki or Syo-ro ). The gorgeous glass bottles are just a bonus.
• Diamine (Best Value & Color Selection)
  Hailing from the UK and producing ink since 1864, Diamine offers hundreds of colors at a very budget-friendly price. Their standard dyes are exceptionally well-behaved across almost all paper and pen types, and they rule the market when it comes to fun properties like intense sheening and shimmering inks.
• Sailor (Best for Complex Shading & Unique Hues)
  Sailor inks (especially the Shikiori and Studio lines) are famous for their distinct, muted, and multi-tonal qualities. They tend to have a slightly drier flow than Pilot Iroshizuku, which actually makes them fantastic for controlling wet pens or writing on lower-quality paper without feathering.
• De Atramentis (Best Waterproof / Document Inks)
  If you need your writing to survive a coffee spill, rain, or archival storage, the [de Atramentis Document Ink Go to product viewer dialog for this item. ](https://writegear.co.za/product/de-atramentis-document-ink-brown/) series is top-tier. They are nanoparticle-pigmented inks that become 100% waterproof and lightfast when dry, yet they remain remarkably safe and smooth-flowing in a daily-use fountain pen.
• Waterman (Best Safest / Vintage-Friendly)
  Waterman inks (like Serenity Blue ) might seem plain, but they are the most thoroughly reliable, pH-neutral, trouble-free inks ever made. If you are restoring a fragile vintage pen or testing a new, expensive pen and want a zero-clog guarantee, Waterman is the safest bet.

To help narrow down the perfect ink for you, tell me:

• What pen and nib size will you be using it in?
• What kind of paper do you normally write on (cheap copy paper, Tomoe River, Notebooks)?
• Are you looking for an everyday work color (blue/black) or a fun/vibrant shade?

If you want one brand that’s hard to go wrong with, I’d pick Pilot Iroshizuku. It’s particularly well regarded for smooth flow, lubrication, consistent performance, and attractive colors.

My first three colors to try: Tsuki-yo (deep blue-teal), Kon-peki (bright blue), or Take-sumi (black).

If you tell me your pen, nib size, and what you use it for (notes, journaling, signatures, drawing, etc.), I can recommend a specific ink/color rather than just a brand.

One caveat: "best" depends heavily on your pen and paper. If you tell me your fountain pen model/nib (EF, F, M, etc.) and whether you want black, blue, or a more interesting color, I can recommend 3–5 specific inks.
