About the TWSBI Diamond 580ALR Piston Filler Fountain Pen - Affogato & Black Titanium

The TWSBI Diamond 580ALR Piston Filler Fountain Pen - Affogato & Black Titanium takes the classic Diamond 580 design and upgrades it with premium materials for the serious writer. While retaining the famous diamond-faceted barrel, this "ALR" version replaces standard plastic components with durable machined aluminum finished in a warm, sophisticated affogato brown.

The standout feature of this model is the ribbed aluminum grip section. Unlike smooth plastic pens that can become slippery during long writing sessions, the matte textured finish provides a secure, tactile hold for superior control. The warm, creamy coffee tones of the aluminum piston mechanism and grip are brilliantly offset by stealthy, modern black titanium (onyx) trim on the cap, clip, and nib, giving the pen an incredibly chic, highly sought-after aesthetic.

Ideally suited for bottled ink enthusiasts, it features a high-capacity piston filling mechanism that holds approximately 1.9ml of ink—nearly 3x the capacity of a standard converter. The clear body lets you see your ink level at a glance, turning the liquid inside into a visual part of the pen's design.

True to TWSBI’s philosophy, the pen arrives in a presentation box with a wrench and silicone grease, giving you the freedom to disassemble and maintain your tool for years of reliable use.
