The Diamond 580 comes with a benchmark piston ink-filling mechanism. It's clear and comes with all detachable parts. The pen is very nicely made. It feels solid and of high quality. The nib is smooth with a little feedback.

The idea behind the TWSBI Diamond 530, 540, and 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.

The main difference between 580AL and 580ALR is that ALR comes with the matte finish, subtile details on the grip and cap.

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.

Nice Demonstrater (Fine Nib)

Love the feel of the nib, and the almost absurd amount of ink the pen can hold. This pen holds my personal record for longest single fill and has seen regular use for almost a year and a half now with no issues, regularly going for a few weeks between fills originally. I have taken to half filling it only to let me swap inks more often.

My pen is showing some light signs of wear after 18 months, with a little of the blue near the finial on the cap rubbing off from where I often hold it since I don't usually post this one. The length makes posting look a little awkward, but the weight of the cap is more than balanced by the aluminum grip section.
