From the manufacturer

One pen for all Occasions
The triplus fineliner is the ideal pen for writing, sketching, painting or drawing
STAEDTLER Box
The practical STAEDTLER box is also a transport box, protective packaging and pen holder. Its lid can be folded down and also serves as a stand-up display. The perfect pen is always within a reach
Excellent Writing Comfort
The ergonomic pen shape fits perfectly in the hand even when writing or drawing for longer periods of time. The triangular shaft ensures a natural, relaxed posture and fatigue-free writing
Guaranteed Reliability
Forgot to replace the cap? This is no longer a problem thanks to the DRY SAFE technology developed by STAEDTLER – even without the pen cap, the triplus fineliner (except neon colors) can lie for days without drying out. This feature extends the life of our products
Super Fine Tips
The ~ 0.3 mm thin line width is ideal for detailed sketches and drawings. The fineliner also impresses with its uniform color application when writing
Writing with Ease
All triplus pens have one thing in common: Their particularly ergonomic triangular shape. It promotes a natural writing posture and relieves the muscles, enabling longer use without overexerting your hand and arm. With a total of eight writing technologies, the triplus family offers the right pen for every application and for every type of writing
Great Color Variety
The triplus fineliner enchants with up to 60 brilliant colors
Washable
Triplus fineliner ink is odor-neutral and water-based. Stains can therefore be easily washed out of most fabrics

- Reviewed in the United States on June 13, 2016Size: 20 Count (Pack of 1)Verified PurchaseI love these pens. I like to use them for adult coloring books, writing letters or making cards for people, or for use in a journal or planner for myself. They are really versatile and can be used professionally or just for fun. The cost if very affordable compared to most high end fineliner pens, and you get many colors that all look different from each other.
As some other people have mentioned, some colors did work better than others. Luckily, though, almost all of mine were perfect and I really only had problems with two of the pens. One of them worked fine at first, and I guess I maybe overused it because it stopped working so well after a bit, but I did notice if I let them sit for a while after using them, they were fine again. So I guess just be gentle with them because they are just pens, not markers. I think that's the mistake I made.
They write great when using them in letters, cards, and journals. Sharpies bleed through paper, so you can't really use those when you need both sides, and regular pens are boring. Somehow I think my handwriting is better with these as well.
I use the original pack I bought so much that I went on to buy the additional colors! If you think you might get good use out of these sorts of things and want a good variety, go ahead and buy the whole pack. I don't think you can do any better for the great price and quality. Any cheaper and I feel like the quality would go way down, and professional fineliners just aren't possible for most of us who just use them casually.

- Reviewed in the United States on March 28, 2015Size: 20 Count (Pack of 1)Verified PurchaseI consider myself a bit of a writing utensil connoisseur, and hands down, these are the best fine-line pen/markers that I have in my collection.
Typically, fine "Sharpie" brand markers have always been my preference for everything from drawing to daily writing, but these have given them a real run for their money...
Pros:
- They're very comfortable to write with (from a woman with petite hands)
- They write very well without any skipping or bleeding
- They're very vibrant in color
- They're extremely thin-tipped for precise writing
- They come in a fantastic case! The case itself is almost worth the money alone...it's very sturdy, and wonderfully designed to keep your pens on the ready while you're working
- The caps have a distinct "click" when you put them back on to let you know that you've securely capped the pen; this might be a personal preference, but I prefer my pens, and markers to have an "audible" cap
Cons:
- If you have a heavy hand, you'll most likely damage the tips; I wouldn't recommend them for a young child or anyone who "smashes" the tips of their pens/markers/pencils/crayons
- If you have a large hand, these might not be very comfortable to use because they may fatigue your hand
If you're particular about finding the perfect felt-tipped pen that writes precisely, and colors vibrantly in an awesome case, these are definitely it!
- Reviewed in the United States on June 27, 2019Size: 20 Count (Pack of 1)Verified PurchaseI bought these for underlining passages in my bible. The red pen I had previously been using bled through the pages like crazy and it took literally a minute to dry, which resulted in ugly smudges everywhere. I was a bit skeptical about these pens. The reviews said they worked well for standard paper, but I didn't see too much about working on thinner bible pages. I was super pleased to find out they write smoothly. All the colors are bold and bright. Yellow is really hard to see because of how bright it is, but I don't use yellow much anyway. Red isn't a very bold red, but more of a reddish orange, but that doesn't really bother me. These pens work magically on thin bible pages. There is a very faint shadow through the back of the page, but it's nothing compared to most pens I've used. The ink also dries almost instantly. As a matter of fact, I wrote with one and immediately wiped it, and there was no smudging at all. The case is very convenient, and opens up to make a stand for the pens so you stay organized.
I included some pictures showing underlining with the fineliner pens in purple and green. The red pen is from a different brand pen I had been using before. You can see that the Staedtler pens write smoothly and boldly, didn't smudge, and can barely be seen through the page, compared to the red pen. I highly recommend these pens!

Great for bullet journaling as they do not bleed through paper. The tips don't mash either!

These are GREAT pens!!
- Reviewed in the United States on February 9, 2025Size: 20 Count (Pack of 1)Verified PurchaseI bought a set in July of 2015 and have not used them much at all but son used them today and they are they work like brand new!!! wow!
- Reviewed in the United States on October 16, 2013I love these pens. I take my notes in law school with them. I use color themes for chapters (blues, greens, purple/pink, etc) in my outlines for studying. I don't know if it'll help my grades, but it sure makes studying more enjoyable!
They don't dry out if left uncapped for awhile, so I can leave them uncapped and ready to switch as needed.
The case is an awesome stand, keeps the colors organized, keeps me from losing pens, and really catches other people's attention.
I'd give five stars if:
* they had more color options,
* there were more usable colors (I have more red, orange, yellow, and black pens than I need in my life; I'd love a wider range of tones or shades... also, a few of the lighter colors a fairly faint... great for highlighting, but harder to read)
* they came in a finer option,
* if the tips stayed as sharp as they begin.
...Don't get me wrong - it's not like they get smushed down or anything, they just tend to broaden slightly and I like a very fine point. (I was previously using Micron pens, which didn't offer as many options and tended to be scratchy.)

5.0 out of 5 stars Love these pens!
Size: 20 Count (Pack of 1)Verified PurchaseI've been looking for the perfect coloured pen to help keep my agenda organized, and these might be it. Their fine tip allows for more precise writing, while the thin profile of the pen body (in combination with the triangular shape) enables you to hold the pen more comfortably and write for longer. The colours themselves are well-saturated, yet they don't bleed through the thin pages of my new planner.
The only thing I don't love about these pens is the case they come in. The case itself is quite thin (not much wider than the pens themselves), but it feels awkward to open and set up all the time. I would prefer a smaller, round/triangular case than the thin, flat case they come in, but that's a minor gripe.

5.0 out of 5 stars Great product!
Size: 20 Count (Pack of 1)Verified PurchaseThis is a great set of brand name pens!
I love the 0.3mm nib, it gives a clear concise line that's easy to see.
Currently these are selling at 43% off for just £15.37. I'm tempted to buy another packet for that reason alone!
Great range of colours. Well worth the money.

5.0 out of 5 stars Me han gustado mucho
Size: 20 Count (Pack of 1)Verified PurchaseEs la primera vez que pruebo la marca y me ha sorprendido. Los rotuladores tienen colores vivos, se deslizan bien y son ergonómicos. Tienen un tacto muy suave, parece que sean de goma pero es plástico. La única pega es el estuche que no se queda como pone pero bueno es lo de menos. Los usaré para estudiar para palabras claves y a ver lo que duran, pero pintan bastante bien desde luego.
