Introduction

The TWSBI (commonly pronounced “twiz-bee”) Mini is like the little brother of the Diamond 580. Take all the parts you love about the Diamond 580 – the modern, industrial design, the transparent barrel, the piston mechanism, the smooth-writing stainless steel nib – then make it more compact for writers who prefer a postable, pocket fountain pen. That’s the TWSBI Mini in a nutshell.

The internal piston-filling mechanism holds about 1ml of ink and can be completely taken apart for thorough cleaning. Instructions and silicone grease are also included to aid in the maintenance of the pen.
