TWSBI Mini Classic Black Fountain Pen

The TWSBI Diamond Mini Fountain Pen – Classic Black combines a compact, pocket-sized design with the practicality of a built-in piston-filling system. Featuring a transparent resin body and cap, complemented by a classic black grip section and turning knob, this fountain pen offers a distinctive look with polished chrome trims.

Equipped with a steel nib, the Diamond Mini is designed for a smooth, dependable everyday writing experience. Its integrated piston-filling mechanism holds 1.17 ml of ink, while the clear barrel lets you monitor the remaining ink level at a glance.

Smaller than the TWSBI Diamond 580, the Diamond Mini is easy to carry in a pocket or bag. Posting the cap extends the pen from 118 mm to 140 mm, providing a more comfortable writing length. Available in six nib options, it accommodates different writing preferences, from precise notes to expressive lettering.
