TWSBI has been on a roll this year, from the Diamond 580 ALR in Prussian Blue to the recently released TWSBI Swipe cartridge/converter fountain pen. Last week, they added the Diamond 580 ALR in Navy Blue, which is a gorgeous deep blue anodized finish that I find can appear quite different depending on the lighting. In some instances it’s a dark navy, in others, a brighter cobalt or even ultramarine!
What distinguishes the Diamond 580 ALR from the standard Diamond 580? The anodized textured aluminum trim. Like the other Diamond 580 fountain pens, as well as the ECO series, the Diamond 580 ALR features TWSBI’s high-capacity piston filling system.
The TWSBI Diamond 580 ALR in Navy Blue is available for purchase now in the T.G.S. Curated Shop, priced at $65 in all nib sizes. Please note that we also now offer interchangeable nib units for the TWSBI Diamond 580 fountain pens, as well as the full line of TWSBI Inks.
The T.G.S. Curated Shop is an authorized retailer of all brands sold, including TWSBI.
Selections from the TWSBI fountain pen lineup, from left: TWSBI ECO in Transparent Green, ECO in Transparent Purple, ECO in Transparent Blue, Diamond 580 ALR in Navy Blue, ECO Clear, and Diamond 580 Rose Gold. Check out the writing samples to find a nib size to match your handwriting.
