What is the STAEDTLER triplus fineliner?
The STAEDTLER triplus fineliner 334 is a capped fineliner with water-based ink, a superfine 0.3 mm metal-clad tip and a triangular barrel. STAEDTLER, based in Nuremberg, describes it on its German site as a fineliner for relaxed writing and drawing, sold in the stand-up STAEDTLER box that doubles as a pen holder.
It’s one of the best-selling fineliners on Amazon in the US. A July 2026 ASINsight report estimates about 10,000 monthly sales for the top listing, and Staples shows a 10-pack at 4.79 stars from 224 reviews.

Galaxus lists a shorter 14 cm for the single black pen. We use JetPens’ measured 16.1 cm, which matches the other lengths in its listing.
Why is the barrel triangular?
STAEDTLER says the ergonomic triangular shape makes writing relaxed and less tiring. The three flat sides sit against the thumb, index and middle finger, and the pen doesn’t roll off a sloped desk.
Officeworks describes the barrel as metallic grey with a color-coded cap, so you can find the color you want in a full box. STAEDTLER also says the colors match its triplus color 323 felt-tip pens (“Mix & Match”), for pairing fine lines with broader fills.
Can you leave it uncapped?
STAEDTLER’s German site says yes: its DRY SAFE ink lets the pen lie open for days without drying out, except the neon colors. The French page makes the same claim. We haven’t tested it yet.
STAEDTLER also calls the pen airplane-safe: an automatic pressure balance keeps it from leaking in flight.
How many colors and sets are there?
STAEDTLER’s German site lists 40 single colors; the US page says 48. In Germany it sells the pens in STAEDTLER boxes of 4, 6 (pastel), 10 and 20, card wallets of 6 to 40, a triangular tin of 12 and a pencil case with 20. US retailers carry similar sets, and JetPens offers sets of 42 and 60 colors.
A blister card of 4 pens in recycled plastic comes in black or blue, for writing rather than color work.
How does it compare with other fineliners?
The triplus is the finer, triangular option; the Point 88 is the colorful hexagonal one; the Micron is the archival-ink choice.
| STAEDTLER triplus | Stabilo Point 88 | Sakura Pigma Micron | |
|---|---|---|---|
| Line | About 0.3 mm | 0.4 mm | 0.15–0.70 mm (003 to 12) |
| Ink | Water-based | Water-based | Archival pigment |
| Barrel | Triangular, metallic grey | Hexagonal, orange | Round, beige |
| Length capped | 16.1 cm | 16.7 cm | Not published |
| Made in | Germany (STAEDTLER) | Germany (most listings) | Japan |
STAEDTLER’s US fineliner page points hand-lettering fans to its range. For lettering, a firm brush pen such as the Tombow Fudenosuke adds thick strokes to the triplus’ fine lines.
Where is the triplus fineliner made?
STAEDTLER’s German and French product pages mark the triplus fineliner 334 Made in Germany. Galaxus lists China as well as Germany for the single black pen, and Germany for pink, so origin may vary by color or batch.
How much does it cost?
It falls in our lowest band, $ (under $5 per pen), when bought in the usual 10- and 20-color boxes. Single pens are also widely sold, and larger sets bring the per-pen price down further.
Frequently asked questions
What line width does the STAEDTLER triplus fineliner write?
About 0.3 mm. STAEDTLER gives the same 0.3 mm line for every color, from a fiber tip held in a metal casing.
Can you leave a triplus fineliner uncapped?
STAEDTLER's German site says its DRY SAFE ink lets the pen lie open for days without drying out, except the neon colors. That's a maker claim; we haven't tested it yet.
How many colors does the triplus fineliner come in?
STAEDTLER's German site lists 40 single colors and its US page says 48. JetPens sells sets of up to 60 colors, so counts vary by market and set.
Is the triplus fineliner waterproof?
No. The ink is water-based, and STAEDTLER says it washes out of most textiles. For waterproof lines, STAEDTLER sells a separate triplus permanent fineliner.
Can you refill a triplus fineliner?
No. JetPens lists the tip as not replaceable and the pen as not refillable, so it's used up and replaced.
Why is the triplus fineliner triangular?
STAEDTLER says the ergonomic triangular barrel makes writing relaxed and less tiring, because the pen sits between thumb, index and middle finger without rolling.
Where is the STAEDTLER triplus fineliner made?

STAEDTLER triplus fineliner or Stabilo Point 88?
Both are capped water-based fineliners in dozens of colors. The triplus writes a finer 0.3 mm line from a triangular barrel; the Point 88 writes 0.4 mm from a hexagonal one.
