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.

Wonderful Pen!

After seeing a bunch of reviews I decided to go with the Twsbi eco and had my partner swing by Yoseka to pick my up the Twsbi Glow Green in an EF nib and it was perfect. I wanted a second and opted for the Glow Purple, also in EF. Highly recommend these pens, the nib writes so smooth and I love how much ink it holds, I love that they're demonstrators and I have been on an airplane with them and as long as you fill the pen full before the flight and have it so the nib is facing up it didnt explode! I was able to write with in on the plane and fly back home totally fine. Plus, they really Glow if you charge it up, so nice.

Love this pen

I previously purchased this pen in different colors and nib sizes so I got this one too. It feels good in the hand and the extra fine nib--my favorite-- writes very nicely.

Thoroughly enjoy the color of the pen as well as its glow in the dark feature. Extra fine is my go to nib size!

one of the best pens I've ever owned

A Grand TWSBI Eco Glow In The Dark Fountain Pen

I think this Twsbi purple glow in the dark fountain pen is better looking than the green version.

Both are grand looking but this purple version edges out the green version.

The materials and workmanship are as always, top shelf grand.

The purple day and bluish night colors are spot on.

I highly recommend purchasing from Yoseka Stationary for your fountain pen, ink, paper and such needs.
