TWSBI Diamond Mini Fountain Pen - Clear

The TWSBI Diamond Mini Fountain Pen – Clear combines a compact, pocket-sized design with the practicality of a built-in piston-filling system. Its transparent resin body, clear cap and chrome trims give it a clean, modern appearance while allowing you to monitor the ink level easily.

Featuring a steel nib and a 1.17 ml ink capacity, the Diamond Mini is designed for dependable everyday writing. Its screw-cap design keeps the pen securely closed, while the postable cap extends its length from 118 mm to 140 mm for a more comfortable writing experience.

Despite its compact dimensions, this fountain pen offers the functionality of a full-sized writing instrument. Available in six nib options, including Stub 1.1 and Stub 1.5, it suits a range of writing preferences, from fine everyday notes to broader, expressive lettering.
