TWSBI Diamond Mini AL

The TWSBI Diamond Mini AL is a compact version of TWSBI's flagship Diamond series, designed to deliver the same dependable writing experience and high-capacity piston-filling system in a more portable form. Featuring the series' signature faceted demonstrator body, the Mini AL incorporates aluminum components in the grip section and piston mechanism, adding durability and a refined metallic finish while remaining fully user-serviceable.

Despite its pocket-friendly size, the TWSBI Diamond Mini AL offers the comfort of a full-sized fountain pen when posted. Its transparent polycarbonate body provides a clear view of the ink level, while the screw-posting cap, stainless steel nib, and integrated piston-filling system combine practicality with the thoughtful engineering that has made TWSBI a favorite among fountain pen enthusiasts.

We have for sale a brand-new TWSBI Diamond Mini AL, available in different nib sizes. It comes complete with its box, papers, and other accessories.
