The ECO is the most affordable model yet from TWSBI. This pen features a piston mechanism, a clear barrel, clear cap and piston knob. The nib is smooth with a little feedback. The barrel is clear and smooth, which has lesser grip than a typical pen. Overall, it feels great holding in hand.

About TWSBI:
TWSBI 三文堂 (San Wen Tong) is one of our earliest collection even before the store. TWSBI started as an OEM manufacturer for different western brands, and around 2009, they decided to start their own brand. With 50 years of experience in pen making, they took to fountain pen forums and gather users’ feedback. It was said that Pelican M800 was the model they were inspired. Most of their pens are transparent, so it’s really fun to see the ink color and it lasts for a very long time.
The name 三文堂 (San Wen Tong) comes from the Hall of the Three Rare Treasures, created by Emperor Qianlong as a memorial to three great masterpieces of Chinese calligraphy. The initials of the name “San Wen Tong” was reversed and thus turned into "TWS". The last letters "Bi" was added with its literal meaning of "writing instruments" in Chinese. Thus combining the two segments, creating TWSBI.
I love the Eco line, as they are almost perfectly balanced in my hand, they usually write super smoothly right out of the box, and they colorways make it easy to try to remember what ink is in which pen LOL. The previous price of $35.99 was much better and I was sad to see them skyrocket to as much as $59.99 lately. That being said, they are still a wonderful intro pen and all of mine have lasted quite nicely over the 3 or so years I've been collecting fountain pens. I only wish I could locate some of the older colorways I have only seen in archived links on retailers websites and blogs. I hope to be able to collect them all one day without spending through the nose on some of the original colorways.
My order was shipped promptly and was expertly packed. This was my first TWSBI fountain pen and also my first stub nib pen, and I am so happy with both. The Eco Black Marble Bronze is a very attractive pen and I am really liking writing with its 1.1 stub. I also ordered two inks, Diamine Writer's Blood, which I have never tried before, and Diamine Oxford Blue, which happens to be one of my favorite blue inks.
I'm so happy that I ordered with Yoseka. I love their social media presence and I believe in supporting local merchants whenever I can. And I can say with all certainty that I look forward to many more future purchases with them.
Love the design and look of this pen
The TWSBI ECO Fountain Pen - Black Marble with Bronze Trim
1.1 Stub arrived and it looks just grand.
The colors are spot on.
I am very pleased with this fountain pen and this store.
Note : I put the postcard with the Yoseka work cats on the store stoop in the same size frame and it is just a grand addition to the wall.
