TWSBI ECO Fountain Pen - Transparent Blue - The Goulet Pen Company
TWSBI ECO Fountain Pen - Transparent Blue
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.

I am new to fountain pens, and this was my first pen that wasn't a disposable, but it converted me. I'm now a fountain pen guy. I love this pen! I write fast, and the flow and M nib keep up with me. No false starts, skipping, or drying out. Its a very wet writer. I paired it with TWSBI blue ink. I love this pen so much I've already ordered a Diamond 580ALR!
Well, I had heard of TWSBI of a sorts, but never did any research about it. Came across Brian’s video about the TWSBI ECO and thought, “Meh, I’ll give it a shot.” WOW!!!! Write out of the box this beauty is amazing for the price. Absolutely a fantastic beginner fountain pen to gift someone to get into the hobby (that I can quit anytime). Love the look and the workmanship is top notch. Will have to explore more of the brand and work my way up. Pretty exciting to find a new line…..as my pocket book will become more unaligned! Great company as well for fountain pen enthusiasts….that can quit anytime. 😜
The experience with this item was amaizing, the only bad thing was the waiting time but it was worth it. The pen is beautiful and I am planing to place another order after some months. The waiting time was verry long and stressfull. The thing that make me sad was the custums because they opened the package. The overall experience was verry good and the only bad things were caused by other factors that can't be controlled by you and I really apreciate the work that you put in them.
Super easy pen to use and maintain... Very smooth writing experience and a great value for the money. Bonus, it looks great as well.
My 3rd fountain pen, and this one honestly outperforms the other 2. It writes beautifully and more smoothly than the others. Love the demonstrator clear visibility - much fun! Definitely will get another TWSBI.
My EDC great flow, smooth. Economical.
My first TWSBI, and a medium point. It is so very smooth, and easy to fill. Writes in reverse for an XF like line, great for drawing. I have 3 Lamy Safaris, 2 F, and 1 M, just got another in XF. I think the TWSBI has a smoother nib, and actually seems finer than the Lamy F nibs. I was worried the grip may be too small, but it is perfect. About the same size without the forced grip, as the Lamy Safari. Excellent service,I'm very pleased, thank you so much!
I love this pen I got the broad and it writes so smoothly! The only thing I don’t like is that the cap won’t stay posted. :(
I love the way this pen writes! I got the broad nib it writes so smoothly ! The only thing I don’t like is that the cap won’t stay posted on mine. :(
Love it, it looks good and love the way it writes - it's like an air hockey puck floating over the air hockey table - no friction.
Heavily used this pen with the M nib for seven years before it stopped flowing, tried everyway to fix it but had to give up. As they are reasonably priced, I picked up two replacements. One for blue ink another for black ink. In them I use MB permanent ink as it behaves perfectly on regular copy paper, it´s waterproof and suitable for the working technical environment. Have a Pilot Falcon for when I’m feeling fancy.
Do I really need to explain this? I don't think so, mate.
Wonderful starter pen. It actually writes smoother and bet than my TWSBI Diamond ALR. Wonderful pen.
I love the way it writes I just wish it accommodated lefty’s more
This is my second fountain pen, my first being a fine point pilot metropolitan. I thought that a Twisbi Eco with an extra fine would be similarly fine to a pilot fine point. Maybe it's because I used a new bottle of kon-peki in the Twisbi and an old bottle of take-sumi in the metropolitan, but the Twisbi extra fine was noticeably broader than the pilot fine. I really like this pen, I just really like very fine points. I hope Twisbi someday makes an ultra extra fine pen.
Easy to order especially for a complete novice - thank you!
I have several ECO's and I see no reason to look elsewhere for quality pens. This one is very pretty and matches the Diamine Havasu Turquoise ink I have in it.
I am new to fountain pens. As a left hander, I was hesitant to spend a large sum of money for a starter pen. Well, I received this Twsbi Eco, and started to use it. I was pleasantly surprised how well this pen writes. Being left handed was irrelevant. This pen writes very smooth and behaves as if it had a several hundred dollar price tag. Since then, I was confident enough to buy more expensive pens. I realized that this Twsbi writes just as well as its more expensive counterparts. Definitely worth every penny.
I have numerous Twsbi Eco pens with the Medium nib (which I really like). I thought I would try the fine nib. It writes very well and does not soak through the cheaper paper that I use often. It is a great pen.
I purchased the TWSBI ECO, in transparent blue. Very nice writer. However, when I tried to clean it, the little plunger (not sure of the technical name) would come loose and remain in the barrel. I was usually able to get it out, but the last time I had no luck. But I did come up with a solution. I took that TWSBI ECO and threw it in the trash. Just tired of fooling with it, and I'll never own another TWSBI.
Great pen, love the transparent blue on it.
I bought that pen specifically to use with Noodler's Bay state Blue. It writes beautifully and seeing the ink slosh in the pen is perfect.
Looks just like In the picture
I love this pen. I bought one on another site and it didn't work so I returned it. I think it may have been a counterfeit pen. I spoke with my art teacher and she recommended this pen. I bought one from the Goulet Pen Company and I liked it so much I bought three others. I love how you can see how much ink you have. It flows nicely and writes smooth. I like colored inks so I have a pen to machine the ink. I highly recommend this pen and this company.
This Eco was just the pen I was looking for to use some FWP shimmer ink in and it's working out perfectly!
The TWSBI ECO is the first fountain pen that I've purchased and used, and it has been a joy to use so far. The packaging is very nice, and the inclusion of the wrench and silicon grease for home maintenance is a nice bonus. I have two, one with Emerald of Chivor ink and another with Pilot Konpeki. They are easy to fill and provide a smooth writing experience on several types of paper mediums. This pen packs a lot of value for a very affordable price.Packing and delivery of the pen from Goulet was wonderful, and I enjoyed the extra attention to detail and quick turnaround on my order. Overall an excellent experience.
Excellent service, a fine writer, arrived on time.
So smooth. Love it.
I've always leaned towards the Lamy Safari, which I love butI wanted to try something new. The price and look of this pen were right where it's at. When it came in and I filled it with inka whole new world. It's an amazing pen and I want a couple more! The nib (in medium) isn't scratchy. It feels buttery smooth when writing.
