The popular TWSBI Diamond 580 ALR is now available in an exclusive Affogato / Onyx finish. The nib, cap, end cap and internal mechanism are plated in luxurious rose gold accents, beautifully contrasting with the dark transparent body.

Thanks to the piston filling system, you can fill the pen directly from an ink bottle. The 580 ALR holds about 30% more ink than the 530 model and can be fully disassembled for easy maintenance. The design of the 580 series reflects the elegance of traditional fountain pens, combined with a modern industrial style – creating a writing instrument that honors the past while remaining relevant today.

TWSBI pens have built a loyal following among fountain pen enthusiasts thanks to their high-quality craftsmanship, innovative features and fair prices. The company continues to release new designs and remains dedicated to offering writing instruments that are both accessible and premium.

About TWSBI

TWSBI is a Taiwanese pen manufacturer known for producing high-quality writing instruments at affordable prices. The name "TWSBI" comes from the phrase Hall of Three Cultures, symbolizing the three key influences at the company’s foundation: East Asian, European and American.

Founded in 1959 as Ta Shin Precision Industrial Co., Ltd., the company originally specialized in plastics and industrial components. In 2009, TWSBI entered the fountain pen market with its own line of pens. TWSBI became known for its innovative approach: providing converters as standard while most brands sold them separately, and using transparent materials that reveal both the ink supply and the inner workings of the pen. This transparency not only adds aesthetic appeal but also allows users to keep track of their ink levels.
