Three and a half centuries of writing instruments
A lot of pen companies happily tout their history. Staedtler has a lineage.
Friedrich Staedtler was born in Nuremberg, the son of a gold- and silverware worker, in 1636. From around 1662, he produced wood-cased pencils with graphite leads himself, to the dismay of Nuremberg carpenters and gunsmiths. They objected because pencil-making crossed their guild territory. Friedrich Staedtler ignored them. Despite a production ban from the Nuremberg Council, the man stuck to his idea.
His descendant, Johann Sebastian Staedtler, founded his own pencil factory in 1835. His pencils caused a sensation at the New York World’s Exhibition in 1853, and within a few years found fans all over the world. Yes, it was a different age.
The Triplus Fineliner is approximately the four-hundredth year of this family’s argument with people who think they know better than a Staedtler about how a writing instrument should work. On the available evidence, the Staedtlers keep winning that argument.
What it actually is
The Triplus Fineliner is a fiber-tip fineliner with a 0.3mm metal-clad tip that produces a clean, consistent line without skipping, feathering, or the kind of existential tip-mushing that plagues cheaper fineliners after a few weeks of use. The metal sleeve around the tip reinforces it against pressure and lateral stress, which is why a Triplus Fineliner used daily holds its line quality considerably longer than competing pens at comparable or higher price points.
The triangular barrel is the other thing worth noting. It’s not just a design choice. The triangular profile sits naturally in a three-finger grip without requiring any conscious adjustment, prevents the pen from rolling off the desk, and makes the pen slightly harder to lose in a drawer than a round barrel because it catches on things. These are not dazzling features, but features of a pen that was designed by people who actually use pens.
The cap is color-coded to the ink — silver barrel, colored cap and end — and posts securely on the back of the pen. The cap snaps with a satisfying click that communicates closure without drama.
Dry Safe
This is what sets the Triplus Fineliner apart from most of its competitors and deserves more than a bullet point.
Staedtler’s Dry Safe technology keeps the pen writing after being left uncapped for days under standard atmospheric conditions. This is not marketing language with an asterisk. Three days uncapped, the Triplus Fineliner wrote like it had been uncapped for the first time. I really appreciated that.
For writers like me who leave pens on desks, in notebooks, in bags, or anywhere that isn’t “carefully capped and stored upright,” this is the feature that determines whether a pen is still useful three weeks after purchase. The number of fineliners that have dried out on my desk is a number I am not prepared to share. The Triplus Fineliner is not among them.
The writing experience
The 0.3mm tip puts down a line that’s fine without being…well, precious, if that’s possible. It’s narrower than the 0.4mm you get with Stabilo’s equivalent, which makes it better suited to small handwriting and detailed annotation, but less forgiving if your natural script runs large. On good paper — the Hobonichi‘s Tomoe River, the Moleskine‘s 70 gsm stock — the line is sharp, dry, and consistent. On cheaper paper it’ll feather a bit, as any water-based ink will, but not more than competitors.
The tip has a slight softness compared to technical drawing pens like one of my faves, the Sakura Pigma Micron. It’s not a brush pen, but there’s a small amount of give that some writers find pleasant and others find imprecise. For journaling, annotation, and everyday note-taking, it’s just right. For precise technical illustration where consistent line weight under pressure is required, a stiffer tip may serve better.
The ink dries quickly and resists smearing. Left-handed writers report better results with the Triplus than with slower-drying inks, though no fineliner is entirely smear-proof immediately after a stroke.
The color range
The Amazon listing is for black, which is the correct starting point. But 48 colors are available, organized into standard, neon, pastel, and nature palettes. For writers who color-code notes, annotate manuscripts, or use the Triplus in a planner or Hobonichi, the color range is one of the best available in the fineliner category. The colors are vibrant without being garish, and the ink is consistent across the palette rather than varying in quality by shade.
The honest caveat
The Triplus Fineliner bleeds through thin paper. Not dramatically, but noticeably. On standard copy paper, notebook paper, and most journal paper it’s fine. On the very thinnest papers, including some Bible-weight notebooks and certain Leuchtturm pages, the bleed-through is visible enough to be annoying on the reverse side. On Tomoe River paper, which is exceptionally thin but dense, bleed-through is minimal. On the Moleskine’s 70 gsm stock it handles well. Know your paper before committing to a full set.
Pros

- Dry Safe technology; survives days uncapped without drying
- Triangular barrel prevents rolling and supports natural grip
- Water-based, acid-free ink; washable from most fabrics
- 48 colors available across standard, neon, pastel, and nature ranges
- Postable color-coded cap
- Made in Germany by a company with 360 years of writing instrument history
Cons
- 0.3mm line width may feel narrow for writers with larger natural handwriting
- Tip is softer than technical drawing pens; not ideal for precise illustration
- Bleeds through very thin paper
- Water-based ink is not waterproof; unsuitable for work requiring water resistance
The verdict
The Staedtler Triplus Fineliner is the kind of product that doesn’t need to announce itself because it has been right for long enough that the reputation precedes it. It writes consistently, survives neglect better than almost any other fineliner in the category, feels correct in the hand, and comes from a company that has been making writing instruments in Nuremberg since the 17th century while various councils and guilds told them to stop.
It is, in short, a very good pen. Buy several.

Frequently asked questions
What is the Staedtler Triplus Fineliner? The Staedtler Triplus Fineliner is a 0.3mm fiber-tip fineliner pen with a metal-clad tip, triangular ergonomic barrel, water-based acid-free ink, and Dry Safe technology that keeps the pen writing after days uncapped. It’s made by Staedtler, a German writing instrument manufacturer with roots in Nuremberg going back to 1662.
What is Dry Safe technology? Dry Safe is Staedtler’s designation for a cap-seal system that prevents the ink from drying out when the pen is left uncapped under standard atmospheric conditions. In practice, the Triplus Fineliner has been tested and confirmed to write normally after 72 hours uncapped. For writers who leave pens on desks or in notebooks, this is a meaningful real-world advantage.
Is the Staedtler Triplus Fineliner good for journaling? Yes. The 0.3mm tip produces clean, precise lines suitable for fine handwriting, annotation, and detailed work in journals and planners. It performs well on most journal paper weights. On very thin paper it may show some bleed-through on the reverse side.
How does the Staedtler Triplus compare to the Stabilo Point 88? Both are popular 0.3-0.4mm fineliners with large color ranges. The Triplus has a slightly finer tip at 0.3mm versus the Stabilo’s 0.4mm, a metal-reinforced tip for improved durability, and Dry Safe technology. The Stabilo has a round barrel and is slightly cheaper per pen. Both are excellent; the Triplus is the more durable choice for daily use.
Is the Staedtler Triplus Fineliner waterproof? No. The ink is water-based and will run if wet. It’s washable from most fabrics, which is useful if you write on your shirt by accident, but not suitable for work requiring water or moisture resistance.
What paper works best with the Staedtler Triplus Fineliner? It performs well on most standard journal and notebook paper weights. On the Hobonichi’s Tomoe River paper, bleed-through is minimal. On the Moleskine’s 70 gsm stock it handles cleanly. Very thin or low-density paper may show bleed-through on the reverse side.
How many colors does the Staedtler Triplus Fineliner come in? 48 colors across standard, neon, pastel, and nature palettes. Sets are available in 4, 6, 10, 20, 30, and 42-pen configurations. Individual pens are also available separately.
