The beloved TWSBI Diamond 580ALR series returns with an even more striking and refined look through the new Onyx Finish. The matte black aesthetic is beautifully combined with luxurious Rose Gold accents, creating a fountain pen with a distinctive presence, premium character, and excellent everyday performance.

The nib, the metal elements of the cap, the internal mechanism, and the rear metal end piece all feature a black finish, resulting in an elegant, modern, and timeless design. The combination of matte black with Rose Gold details gives the pen a particularly sophisticated appearance, while preserving the practical and industrial character that defines TWSBI.

The TWSBI Diamond 580ALR retains its signature Piston Filling System, offering generous ink capacity, consistent ink flow, and outstanding reliability for both daily use and extended writing sessions.
