TWSBI Diamond 580 ALR Fountain Pen - Caribbean with Onyx

We are so excited to announce Twsbi's newest Diamond 580ALR Caribbean with Onyx! The Diamond 580ALR has aluminum accents and a ridged grip.

The Diamond 580 is a workhorse of a pen, featuring a piston filling mechanism, a smooth-writing steel nib, a screw-on cap with an interior cap to keep ink from drying out, and a beautiful faceted demonstrator body.
