The TWSBI ECO-T fountain pen boasts an incredible value with its piston filling system and affordable price. Like many other TWSBI fountain pens, it features a crystal clear acrylic barrel so you can see your ink level, and a clear cap. The pen cap has an inner cap to ensure a perfect seal when stored away. It is completed with silver trim and a silver stainless steel nib. The ECO-T differs from the ECO in that it has a triangular grip section for ease of holding the pen, and triangular shaped cap and piston knob instead of hexagon.

TWSBI's belief is that it is important to allow the user to disassemble and reassemble the pen and completely experience the traditional aspects of owning and using a fountain pen. These pens also come packaged with a wrench and silicone grease. Neither of these accessories are intended to be used immediately, as they are for long-term care and maintenance. Additionally, please use extra care if you choose to disassemble the nib and feed, as the feed is very fragile.

Meh!

To be honest I am glad I didn't get this one first. It's mediocre at best and if I would have gotten this before I got one of the other pens. Twsbi Eco- Creme' or Eco Black Marble. I would have not even invested in another Twsbi Eco. I wanted clear to match any ink at any time but the cap doesn't even stay capped onto the pen and over feels cheap compared to the others I have.

Great overall pen for the price

Good feel for grip and writing. Reliable construction. Hold a tone of ink. Watch the "How to" videos on assembly and disassembly.

This pen is a drag….

This pen has a EF nib that is quite scratchy and skipped frequently. A few passes over leather strop has nib feeling less scratchy. Nib feels like it was a last of shift good enough nib. Not as smooth or wet as the other EF TWSBI nibs I have or have used.

Held off buying an Eco due to bad press.

Held off buying an Eco due to bad press about cracking. Honestly though, I LOVE this pen. It is weighted just right and looks gorgeous with Diamine Pink Glitz in the tank. I ordered the stub nib but will likely purchase another with M nib, or perhaps upgrade to a 580 so I can swap nibs. Definitely worth purchasing, writes beautifully!

Works to a T

I got this pen to see just what the difference between the ECOs was. So far I can't tell the difference between the two! Both are fantastic writers, feel good in the hand and look good! Recommended!

Solid Everyday Writer

The ECO-T is a solid everyday writer. Comfortable to hold. Ink flow always starts immediately. Smooth on the paper. Great performer without breaking the bank,

TWSBI Eco T

I'm just starting my fountain pen obsession and this was the front-runner on my list. I must say, I love the quality of this pen and the way it feels in-hand. However, I think after using it, I prefer Japanese nibs, since this EF one seems more like a Fine-Medium. (German vs. Japanese) However, the service from Goulet Pens is stellar and I will be returning for future purchases!

The best writer I own!

When a $32 pen writes better than my $250+ Pilot, it deserves a review. This pen is butter smooth, just the right amount of wet, and forces VERY minimal feedback on me in any situation. I can't say enough good things about it. Buy without hesitation � you won't regret it. This lead me to buying one of every TWSBI model they make. Want to know what my second best writer is? The TWSBI Vac Mini. Great value in these!

Pretty good.

Using it with the Diamine Shimmering seas is a great combo. Nice and flowy, glitter doesn't impede it too much, but I have to admit it skipped a little bit for me. Overall, good pen.

Great pen

This one is so far the best pen I have owned! It is a large pen but very comfortable, writes better than my pilot fountain pen. Overall an incredible value!

Excellent Pen

I had this exact pen and either I lost it or someone helped themselves to it. Either way I had to replace it. Such a nice writer with a huge ink capacity and beautiful demonstration of the ink color all make this pen a must have winner!

Great starter pen

This uses German Nibs. I got mine in fine, it feels like a 0.7 Pilot G2 Gel Pen. This is my first fountain pen after watching many videos. I absolutely love it and feel like anyone starting out should be happy with it. I recently got a TWSBI Go in Extra Fine and I'd recommend that size nib for something close to 0.5 Pilot G2 Gel Pen (since the two use the same nib)

Not my favorite TWBI

I love my other two TWBI fountain pens but this one has hard starts and skips and it has frustrated me to no avail.

Fragile grip

This pen is an amazing pen, but I've noticed that all TWSBI Eco's have a very thin and fragile grip. I've owned two, and fractured both in the first 3 months of owning them. I don't think I use an overly forceful hand, but maybe I do? Either way, if you're in for the durability, and don't mind sacrificing some ink capacity, you should get the TWSBI Go instead.

I love the TWSBI pens, the ease of use, and the generous ink capacity. It is also really nice that the ink cartridge is built into the pen

Love This Pen !

First of all, Dave Snyder was not the purchaser of the Eco-T Fountain Pen, I was the one who sent it to Dave Snyder (as a little gift) and he loves the pen - he loves the quality for the price (so do I) and has used it many times with great satisfaction ! Excellent choice of product to carry for Goulet Pens. Joanna Snyder (Dave's wife)

Solid, good quality, pen.

The ECO-T is a well designed and sturdy pen. It is easy to fill the pen with a generous amount of ink. Its large reservoir allows you to see how much ink you have to work with with no problems. Its visible reservoir is also a good conversation starter, especially if you are using a non-traditional ink color. I like the pen is a good size without being too broad in the barrel or too heavy. This pen fits in my hand very well, even without posting. I went with the stub 1.1 nib, and I really enjoy how the pen writes. The nib gives my writing a bit of character without being too flashy. Ink flows well through the nib and it puts down a good sized line without being too bold. Overall, I really like the pen. I would recommend it to anyone who is looking to get a good starter fountain pen, or would like to step up from some of the cheaper

Have 3, will get more

A phenomenal pen at a good price. Perfect for a first fountain pen. I got the Fine nib, which works well on inexpensive paper (ruled loose-leaf and pad paper from Staples, etc), without bleeding or feathering. So far I have three, each dedicated to an ink: one has Waterman Serenity Blue, one has Pilot Yama-Budo, and one has (permanent, pigmented) Sailor Kiwaguro black. All three work well. I've looked around and I can't really see a better demonstrator pen. Maybe the TWSBI 580. And you can pay a LOT more and not get a smoother, more-controlled writing experience. Only potential downside is complaints I've seen online about cracks developing.

A dear friend took one look at a note I'd written with my TWSBI and exclaimed: I need one of those! Happy birthday, Carol.

More than a starter pen

This is a very lovely pen. I bought the Eco-T, because I liked that it was slightly less bulky looking than the Eco which has a hexagon shape while this one is more of a smooth triangular form. I like the demo quality of it. I liked being able to see how it works on the inside, but also having a clear view of how much ink is left in it is helpful. It hold a great amount of ink, too, so I can write for days, and it's a smooth writer. I got it with an extra fine nib so I can practically use it on any quality of paper. And the quality of this pen in itself is superb! It feels like it will last for many many years which for what you pay for is a great deal. Absolutely one of the best.

Great product!

For my first fountain pen, it's very easy to use and a great introduction to the fountain pen world. My only issue is that the extra-fine nib that I purchased with it, looks more like a medium to me and I was hoping for a thinner writing experience. Other than that, it writes smoothly and great.

Really Awesome!

I'm really enjoying this pen. I can use it on any type of paper, and not many of the paper fibers get clogged on the nib, like my Pilot Metropolitan does. My only issue is that the ink is a bit runny, but that's no big deal. I really love this pen and the simple plastic case that this comes with.

great beginner stub nib pen

I find this to be a great pen with excellent ink capacity. I've never used a 1.1mm stub nib before so the price for this TWSBI Eco-T was just right. It writes very wet, and makes shimmering/glimmering inks look INCREDIBLE. I used Colorverse Scorpii, which took quite a while to dry, but worth the wait for any calligraphy beginners and enthusiasts.

A new favorite pen!

Wow! The TWSBI ECO T suite me to a T. I bought the clear demonstrator, which arrived in record time. I inked it up with Noodler's Blue and have been loving the writing experience as well as the visual pleasure of seeing the blue ink through the clear pen barrel. The nib is outstanding!!! I love stub nibs and this 1.1 stub nib writes so smoothly (butter smooth) and so comfortably. It has become my favorite pen � as delightful as my 40 year-old gold stub nib 320 Montblanc pens, and that's saying something! The pen holds a serious amount of ink and starts up every single time. It's a wet writer, which I love, and I imagine the Noodler's ink contributes to that writing experience. I like the T model with its triangular shaped grip section. It feels good for the way I hold my pen (traditional thumb and first two fingers). The smooth plastic also feels comfortable. The pen is so pretty in its pristine newness that I am storing it in a fabric sleeve to keep it from getting any scratches. Just seems like a good idea. Being made of plastic, a little extra protection is worth it to me. In summary, I am completely delighted with this pen and with Goulet Pens' exceptional service and incredibly fun and helpful videos!

Love this pen!

I ran to the mailbox when I got the notice my TWSBI 1.1 mm stub had been delivered. I have been riding with it all day and have not been disappointed. I filled it up with DIamine in Twilight and it is a smooth and delightful writing experience. A great pen for a great price

TWSBI ECO-T -- A Worthy Addition

This is my second TWSBI ECO. After obtaining an ECO, I saw the ECO-T on Goulet's website. Just for curiosity, I bought it because I wanted to see the differences between the pens myself (and also get a second wrench since I foolishly threw the first one away.) I am very happy with both of the pens, although I find the extra fine point on the ECO-T a little scratchy but the fine point on the ECO works beautifully. Smooth Ink flow. Change the nib, and I'm sure the ECO-T will perform the same as the ECO. Aside from, the nib size and a slight comparison between hexagonal and triangular shapes at the ends, I see no difference between them.

This pen blew me away it writes like a charm. Hardly any resistance, not too dry, not to wet a perfect nib. Instant favorite.

one of many

TWSBI pens are at the top of their game with each iteration, and the lower priced models easily compete with much more expensive pens where it come to the important part: putting ink on paper ... sure, you can drop a boatload of your hard- earned, over- taxed, God entrusted dollars on a really expensive pen, but there's a line where you're paying for the name and the prestige. TWSBI stays clearly on the utilitarian side of that boundary, and their ECO does it very well: maximum value for the dollar spent!

Frequently Asked Questions

How do I fill a fountain pen with ink? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

It depends on the pen's filling mechanism, which you can find in the Technical Specs section above. 

Here's a quick definition of the most common filling mechanisms:

  • Cartridge - A small, disposable, sealed plastic reservoir that holds fountain pen ink. These come pre-filled with ink, and typically you just push to insert them into place and you'll be ready to write! Check out our quick guide here.
  • Converter - A detachable and refillable ink reservoir that allows you to use bottled ink in a cartridge-accepting pen. Typically you will install the converter into the grip section, dip the nib/feed into the ink, and twist or pull the converter knob to draw ink into the converter. Here's a video for how to fill a cartridge/converter pen using a LAMY pen as an example.
  • Eyedropper - A pen that utilizes the entire barrel as a reservoir for ink. Ink is directly filled into the barrel, allowing for a high ink capacity. Here's a video on how to do it!
  • Piston - A type of filling system that uses a retracting plunger inside a sealed tube to draw ink into a pen. They are typically either twist or push-operated. These pens cannot accept cartridges or a converter, and only fill from bottled ink.
  • Vacuum - A push-style piston that uses pressure to fill the large pen body with ink. They seal the ink chamber when closed, making it ideal for flying without risk of leaking. Check out our video on how to use a vac filler here.

Check out more info on these filling mechanisms including a video on how to fill each one on our blog.

How do I clean this fountain pen? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

It mostly comes down to flushing out the pen with water, and sometimes a little bit of pen flush if the ink is really stuck. 

We put together a blog post with step-by-step instructions, or you can watch the video here:

We recommend a good cleaning every 2 weeks, and any time you change ink colors. Water will usually do the trick, but we recommend you use our Goulet Pen Flush if the ink has been left in the pen for a while and could have dried up, or when you’re switching ink colors.

For even more information about fountain pen cleaning, check out our Fountain Pen 101 video blog post.
