TWSBI Pens

TWSBI
If you are looking for a TWSBI item not listed on our website contact customer service. We are often able to get TWSBI pens and inks not listed.

TWSBI has been created from the Chinese phrase "San Wen Tong" which means "Hall of Three Cultures". This phrase brings to mind the Hall of the Three Rare Treasures created by Emperor Qianlong. The initials were reversed creating "TWS" and "Bi" was then added which literally means "writing instruments". The result is TWSBI.

The Ta Shin Precision company has over 50 years as an OEM manufacturer with plastics and metals. They have created a wide range of products and TWSBI was born under the company selling writing instruments as their own brand.

TWSBI offers a high-quality product for a reasonable price allowing writing instruments to be loved by many. They create many different aesthetically pleasing designs that look great but write just as well.

The TWSBI mission is to inspire and recapture the romanticism of art and literature...starting with the pen.

To achieve this mission they are dedicated to manufacturing the highest quality and precision writing instruments, tailoring products to their customer's wants and needs, and providing sincere and dedicated customer service.

Pen Chalet is an Authorized Dealer of TWSBI pens and writing instruments.

Customer Reviews

ECO-T Special Edition
I use the Fine or Medium nibs depending on ink. This pen in fine writes beautifully as all TWSBI pens do. Industrial design perfectly executed and finished - AND very reasonably priced! I like the fact that their acrylic bodies don’t scratch as easily as say - Lamy. Keep in a sleeve and they look good as new for years. And the disassembly for cleaning is great when using “difficult” inks. Win,Win,Win.

Everything you could want in a highly functional pen. The grey makes it aesthetically pleasing as well. Love the Medium nib. There is nothing to dislike in this pen.

Diamond 580ALR
The top sub $100 piston in my opinion. Nothing else comes close...some $200+ don't even match this.

Diamond 580 Smoke Rose Gold
The looks of the TWSBI 580 Rose Gold are stunning! The smoke cap and end paired with the rose gold work together give this pen a subdued look of elegance. I’ve received many compliments and “What’s that?” queries about the pen.
Differences about this pen that go beyond looks are the use of metal in the piston assembly, similar to a 580 AL or ALR, but a plastic, smoke-colored section. It’s a hybrid of the standard 580 and AL/ALR versions. I was concerned about the balance of the pen as the back metal piston assembly weight is not offset by a metal section as per a 580AL/ALR, but I haven’t really noticed the difference yet.
It's a great writer with a Medium nib, but I’d sure like to try a Broad with this pen.
I heartily endorse it!

Diamond 580AL
The TWSBI 580 was a completely pleasant surprise. It writes like a dream, has heft, and its major plastic and metal components are all well-crafted. Instantly, one of the favorites in my collection.

Gorgeous pen; the color accents are darker than "Rose" would lead an English speaker to assume. Love the faceted barrel. Has good weight to it. EF nib worked great out of the box, so this is twice now that TWSBI has exceeded my expectations.

I have the TWSBI Blue-Black ink. This iron gall ink writes smoothly, behaves itself on the paper, displays the classic color shift as it dries, and is highly water resistant in my testing. The top from the TWSBI Vac20A ink bottle will replace the threaded cap, making for a very convenient way to fill a TWSBI Vac700R or Vac Mini and minimizing oxygen exposure. It is a very fine ink in a very convenient package.

To revisit my previous review:

I erred. I did not flush the pen before I filled it the first time. Now, having flushed it in the course of changing inks, I can say it is spot-on for the nib width. Full marks.

My first fountain pen. The pen is working well. I am learning how much fun changing inks and experimenting with color can be. I will be buying more TWSBI pens with different nibs to continue my experimenting.

This pen writes very smoothly and I swear holds an entire jar of ink in one go. Only drawback is the piston twists easily and could drip if turned. Will buy other styles of this pen in the future.

ECO White Rose Gold
I have only wonderful things to say about this TWSBI fountain pen (actually ALL TWSBIs). It is a solid, modern fountain pen - well designed and beautifully made. This particular pen is accented with rose gold trim which gives it more of a corporate look, while still maintaining its contemporary look and style.

it's so beautiful. it's absolutely stunning, i'm blown away. it's probably the prettiest pen that i own, and it works FANTASTICALLY, but what do you expect? it's TWSBI. sad that it was about $20 extra (when compared to a normal eco), but it was 100% worth it.

Vac700R
This thing is huge, capacity-wise. And it has an impossibly smooth glide across the page, letting it move as though on wings while I transfer my thoughts to paper.

My initial fill was with Heart of Darkness. With that ink and a medium nib, it wrote more like a broad. Still glassy smooth, but wider than it was marked. I replaced the nib with a fine, and got the line width I wanted.

I have a few assorted TWSBI pens in my collection. I like them all. They are beautifully made and great writers. So...when the ECO and ECO T models came out, my OCD side came out and I have to have each color. To go with whatever shirt I'm wearing, of course! I get compliments every time I carry one. The "demonstrator" barrel always grabs their attention. (Yes, the ink color coordinates with the pen.??) Always glad I shop at Pen Chalet!

Really nice empty bottle. Thick glass feels like it would be hard to break. Perfect for mixing up a batch of your mix or taking some ink to the office. Cap is great. Will not leak.
