TWSBI – Fountain pens and Accessories

TWSBI pens showcase innovative design features, including transparent resin bodies for easy ink level monitoring, and chrome-plated stainless steel accents for a sleek, modern look.

TWSBI Fountain Pens

Their smart construction makes maintenance, cleaning, and even customization a breeze. Select models allow you to swap nibs to suit your writing style.

Available in various nib sizes, including EF, F, M, G, and Stub 1.1 mm, so you can find the perfect fit for your handwriting.

They offer excellent ink capacity, with some models holding up to 1.5 ml, thanks to their internal piston filling system, which draws ink directly into the reservoir.

Plus, the ink stays fresh longer thanks to the o-ring and other sealing features built into the cap.

Some of their most popular models include:

TWSBI ECO: Clear body with a colored cap and matching accents. Stainless steel nib.

Its piston system helps reduce ink waste and delivers long-lasting performance.

Perfect for beginners thanks to its ease of use — and a solid choice for seasoned writers who value quality.

TWSBI Diamond: The 580 model holds up to 30% more ink than other refillable pens, making it ideal for uninterrupted writing sessions.

Enjoy the best of classic writing and modern premium design in one pen. Fully disassemblable for easy cleaning and maintenance.

Smooth threading, a comfortable grip, and an enhanced barrel section make the Diamond a true standout.

Alongside its wide selection of pens, TWSBI also offers a range of fountain pen accessories, including interchangeable nibs, spare parts, glass ink bottles, and premium inks.

We especially recommend their inks for their universal compatibility with other fountain pens. They’re water-based, non-toxic, and designed to keep ink flow smooth. Enjoy vibrant, personalized writing with easy maintenance.
