The TWSBI ECO 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 marbled white cap and finial. The pen cap has an inner cap to ensure a perfect seal when stored away. It is completed with onyx black PVD trim and a matching stainless steel nib.

The Carrara color features a new coloring technique in the injection molding process to create unique patterns and colors. Every single pen will be unique and we cannot honor special requests.

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.

We do our best to photograph the pens to show how they will appear in person, but due to the nature of the material, there will be some variation in the pattern seen here. This adds an element of uniqueness to the pen, with no two patterns being exactly the same. We cannot honor special requests.

Excellent color variation

Excellent color variation. The stub nib is fantastic even though I’m learning slowly. Paired excellent with pelikan turquoise.

Excellent!

The marbling is beautiful. I got a nice heavy dose of color in my pen and the stub nib just gushes ink like ink is supposed to.

I love these eco pens

I love these eco pens, they are fantastic for shimmer inks. I’m a sucker for the black trim so when I saw this I had to have it. Performs as expected.

It is an Eco! Nuff said

It is an Eco! Nuff said. The best fountain pen money can buy for $50-$60. I now own 12.

One of my favorite TWSBIs

This TWSBI Carrara has quickly become one of my favorite pens. It’s the onyx trim and nib. I just love it. The Carrara is a great neutral. I can ink it with any color. I got it with a medium nib and it’s as smooth as butter.

Beautiful & neutral colors & another perfect writer

Like Jason W., I really didn't need another TWSBI ECO, but I bought it anyway. I love Carrara marble, and I really wanted something that was ink-neutral. Any ink color would work in this pen. The nib is very smooth, as are all my TWSBI nibs (I prefer medium). And it's just plain fun. I filled my pen (after rinsing out with water) from a sample vial of Pilot Iroshizuku Syo-ro (really like the ink, too). If you're buying your first TWSBI you'll love this pen. If you already have 5 or more, you'll love this pen. These special versions are gorgeous. TWSBI is doing a good job of keeping the ECO very interesting!

Oof!

OMG it's gorgeous! I didn't _need_ another Eco. But I had to have this. If they ever make a 580 in this style I'm getting one! And I said that with full Peregrin Took energy.

Gorgeous and as lovely as the many other TWSBI Eco pens that I have

Gorgeous and as lovely as the many other TWSBI Eco pens that I have. Can’t beat the ink capacity, and I love the colors in the caps. This is the first one with a black nib that I’ve purchased, and I love love love the swirly monochromatic pattern accented by the black hardware. Fun special edition!

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.
