The idea behind the TWSBI Diamond 580 was to go back to basics and capture the simplicity and elegance of traditional writing instruments.

In recent years, the development and modernization of writing instruments has resulted in traditional writing instruments, such as fountain pens, falling into obscurity.

It was our goal to bring the past back to life by creating a traditional fountain pen that even modern day society can appreciate.

TWSBI Diamond 580, a classic fountain pen with a piston ink-filling system.

By fusing the traditional mechanisms of the fountain pen with a modern industrial design, we have created an eye-catching fountain pen that is simultaneously appreciative of the past and relevant in the present.

The Diamond 580 comes with a benchmark ink-filling mechanism and has all detachable parts.

We felt that it was important to allow the user to disassemble and reassemble the pen and completely experience the traditional aspects of owning and using a fountain pen.

After 40 plus years as an OEM manufacturer for different global brands, Ta Shin Precision decided to start selling under their own brand, and thus TWSBI was born.

TaShin Precision has over 40 years of experience in manufacturing with plastics and metals. Early products ranged from toy lego parts to high end writing instruments. This knowledge trickles down into every product TWSBI has to offer.

TWSBI\'s name stands for the phrase "Hall of Three Cultures" or "San Wen Tong" in Chinese. The character "Wen" translates into language and culture.

The phrase "San Wen Tong" also brings to mind 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 phrase "San Wen Tong" was reversed and thus turned into "TWS". The last letters "Bi" was added with its literal meaning of "writing instruments". Thus combining the two segments, creating TWSBI.
