The best everyday fountain pen ink doesn't need to be the most dramatic or the most expensive. It needs to flow reliably, dry in a reasonable time, behave well across different papers, and make you want to pick up your pen. These are the inks our customers reach for again and again, chosen from our bestsellers over the past year.
1. De Atramentis Document Ink - Black
If you need one ink that does everything, this is it. De Atramentis Document Ink is a pigment-based, waterproof, and lightfast ink that dries permanently on the page. It's the go-to for anyone who needs their writing to last, whether that's journalling, correspondence, or anything that might get wet. It flows smoothly, cleans up without drama, and produces a deep, consistent black. Our single bestselling bottled ink by revenue.

2. Diamine Alexandrite
Our bestselling ink by units sold and it's easy to see why. Alexandrite is a blue-green that shifts depending on the light and the paper, with strong shading and a hint of sheen in broader nibs. It's characterful enough to be interesting but restrained enough for everyday use. Works beautifully across a wide range of papers and nib widths. A genuine all-rounder.
3. Diamine Forever Ink
Diamine's Forever range is designed for permanence, water-resistant and fade-resistant, making it a practical choice for documents, notes, and anything you want to keep. The range covers a broad palette, so you're not limited to black for archival-quality writing. Strong sales across the range reflect how many of our customers are looking for reliability alongside colour.
4. Pure Pens Ink - Celtic Sea
Our own Celtic Sea is one of the most popular inks we make - a rich teal-blue inspired by the waters off the Welsh coast. It has excellent flow, good shading in broader nibs, and sits comfortably between blue and green without committing fully to either. Made in South Wales, it's a colour with a story behind it. Our top-selling Pure Pens ink by revenue.
5. Diamine Lady Grey
A soft, warm grey with just enough blue to keep it from feeling flat. Lady Grey is the ink for anyone who finds black too stark for everyday writing but wants something more sophisticated than blue. It reads clearly on white paper, photographs well, and pairs beautifully with cream or ivory stationery. One of our most consistently popular Diamine inks.
What Makes a Good Everyday Ink?
The best everyday inks share a few qualities: reliable flow that doesn't skip or hard-start, reasonable dry time on standard paper, easy clean-up, and a colour that stays pleasing over long writing sessions. Waterproof or water-resistant inks are worth considering if your notes matter, a spilled glass can undo a lot of work with a standard dye-based ink.
