TWSBI Diamond

The TWSBI Diamond 580 features a striking diamond faceted barrel that prevents your pen from rolling off the table, whilst the transparent construction allows you to see the piston fill workings and remaining ink levels. Sitting comfortably in the hand, this durable, lightweight fountain pen is finished with a screw-close cap and rubber O-ring to prevent leaks and drying. Match the Diamond 580 with the TWSBI Diamond Ink Bottle for an easy, fuss free filling experience. Available in a pocket and standard size, as well as a variety of nib sizes.
