TWSBI ECO Fountain Pen - Rootbeer w/ Bronze Trim - The Goulet Pen Company
TWSBI ECO Fountain Pen - Rootbeer w/ Bronze Trim
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 transparent brown cap and finial, named Rootbeer. The pen cap has an inner cap to ensure a perfect seal when stored away. It is completed with bronze trim and a bronze-colored stainless steel nib.
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.

The most beautiful pen. I love the color and it handles my shimmer ink really well. I got the 1.1 stub which took some getting used to but I love using it for titles/headings in my journals
Writes smoothly, perfect amount of ink deposited on the paper. Filled it with Coloverse Coffee Break and it looks so good!!!
This is an excellent pen -- it writes beautifully (stub nib), is comfortable to hold, and I love the "illuminated" brown color with bronze trim. It's well worth the price, and I heartily recommend it!
Simply stunning color combination. The transparent brown of the rootbeer colored cap and the bronze metal trim makes this one of the most attractive TWSBIs to date (in my opinion).
One great thing about TWSBIs is how well they keep the nibs from drying out -- I can set them aside for weeks, even months, and they start up writing as soon as I pull off the cap and set pen to paper.
Quick pleasant transaction.
I've gone down the Twsbi rabbit hole and this is my 3rd pen. So now I have one of each: the Vac700R, the Diamond 580, and this Eco. I was surprised at how much I like the medium nib, since my preference is usually extra (extra) fine pens. It's a well built pen, nice and lightweight. The biggest difference for me between the Eco and 580 is the interchanging nibs and the weight. If you know you're not going to switch your nibs, I think you'll like the Eco
Love the ECO series. Root Beer has a lush appearance and feels great as I write. Still struggling to get the ink reservoir filled without bubbles (pen skips) … small issue. Overall, ⭐️
I got these for my best friend and me. We love them so much! The order was easy and shipped quickly.
Gorgeous packaging for this pen!
This is my first TWSBI and I am a huge fan. I bought the and I love the size. This pen is a dream to write with. I paired it with Robert Oster Caffe Crema ink, beautiful together. I will be purchasing more.
Beautiful! Writes smoothly. Great addition to growing my TWSBI collection!
Gorgeous fountain pen! Twsbi never disappoints.
Always did like the TWSBI ECO. This one is no different.
Love this pen and love this shop!
I had sworn off buying every new color of pens I already owned, until this rich brown tempted me beyond what I could resist. All my Ecos are opaque but Twsbi hit it out if the park with this borwn. As for the pen itself, it's an Eco, what's not to like?
This is my first TWSBI. I've read positive reviews about the brand and wanted to find out for myself. I like the pen! It's in my every day carry three pen case along with my Pilot Custom 823 and Opus 88.
Nice pen for the cost. Writes smooth. No issues with thr pen
The root beer color, in person, made me smile!!! I love writing with these 1.1mm stubs. How can anyone just have one when there are so many fun ink colors and the Eco is so easy to fill.
They are great little pens for traveling and every day use!!! Not expensive and they do the job!!!
Beautiful pen, writes super smoothly and isa gorgeous color. Twsbi did it again!
Love it
Love the Twsbi Ecos - they give a nice line. The rootbeer color is right on the nose!
I've bought several pens from Goulet Pens. TWSBIs are my favorite...excellent quality materials, excellent craftsmanship, reasonable prices, and above all the ink does not dry out quickly. I can pick up an inked TWSBI that has not been uncapped for more than 2 months and it writes smoothly immediately and plenty of ink still inside....amazing...no other ink pen in my possession does that.
Love this fountain pen. Beautiful color and writes so smooth
The design of the Root beer is beautiful. The semi-transparent color is striking. The nib (F) flows perfectly with minimal feedback.
Got the email notice that the new Rootbeer ECO was available. Ordered it immediately. Checked back later in the day and it was already sold out. Received it in the mail a few days later. Gorgeous in person. I especially like the bronze nib and trim with the translucent cap and grip. Inked it up with Writer's Blood. Writes perfectly with the EF nib on the Paperage and Leuchtturm 1917 notebooks I have. Home run, TWSBI.
