TWSBI Diamond Mini AL Silver Fountain Pen

The TWSBI Mini comes with a benchmark piston ink-filling mechanism and has all detachable parts. Like many other TWSBI fountain pens, it features a crystal clear acrylic barrel so you can see your ink level, and a clear cap. It is completed with silver trim and a stainless steel nib.

Roughly the same height as an iPhone 5 when capped and stored away. Slightly longer when cap is posted on the pen (perfect length for writing when cap is posted on the back). 

nib: stainless steel

ink: bottled ink only
