The TWSBI Diamond 580 AL R Navy Blue is one of the most affordable fountain pens with piston filling system on the market. The pen is made of transparent polycarbonate which shows off the inner workings of the pen as well as the colour and amount of the ink inside. The modern look is completed with chrome plated details. The cap is smooth while the barrel is faceted. The gripping section, connector and screw of the TWSBI Diamond 580 AL R Navy BLue are all made of blue metal. The TWSBI logo is visible at the top of the cap.

The TWSBI Diamond 580 fountain pen has a polished stainless steel nib engraved with the TWSBI logo, available in several sizes.

TWSBI fountain pens can be entirely disassembled for the purposes of cleaning and servicing. Instructions and necessary tools are supplied with each TWSBI fountain pen. Please note that the disassembly feature is only there for experienced users and is not necessary for normal use. Disassembly is at your own risk!

With a history of more than 40 years of manufacturing, including producing high-end pens for other brands, Ta Shin Precision decided to start selling under their own brand, TWSBI. The name TWSBI is made up from TWS and BI. ‘TWS’ is the reversed initials of the phrase ‘San Wen Tong’, translated Hall of Three Cultures, and ‘BI’ literally means writing instrument.

    This is a simple and elegant writing instruments. I love this pen for nice design, piston filling mechanism.The nib is perfect, fine, firm and smooth.One of the best fountain pen values on the market.

  2. Thanh Nghia Vo (verified owner)

    Great pen for the price. The filling mechanism works great, and the see-through reservoir shows off the ink perfectly.

  3. Juan Fco Trujillo C (verified owner)

    Bello y grande plumín, le cabe bastante tinta. Me gusta en nib mediano porque siento un mejor deslizamiento en el papel.
    De las plumas accesibles está en el top.

    Gran producto, no lo pienses más.

    TWSBI’s 580 line is my go to daily writer! None of them has ever failed me! I’ve had issues with ink flow in the eco in the past but this model is *chef’’s kiss*. Every time TWSBI releases a new color for the 580 line, it’s always a must buy for me. The quality and price cannot be beat.
