Simplicity and Elegance
The TWSBI Diamond 580 Fountain Pen is different from many fountain pens because it fills with a piston-fill mechanism instead of cartridges. Simply unscrew the end cap, dip into ink, twist the end cap, and the barrel of your pen is filled with ink, ready to write.
The Diamond 580 is crafted of durable, scratch-resistant resin and features a clear transparent body. The No. 5 nib section can be unscrewed for cleaning or swapping in a different nib size.
Ideal for beginners and experienced fountain pen users alike, the TWSBI Diamond 580 is a pen that feels more expensive than it is.

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.
TWSBI aims to create the highest quality and precision writing instruments, with a goal to inspire and recapture the romanticism of art and literature, starting with the pen.
