Diamond 580 Fountain Pen Iris * TWSBI

 TWSBI's showpiece is the Diamond 580. The 580 has a luxurious design with angled surfaces in the material as in real diamond work. It comes in two versions and different color combinations. The transparent body is equipped with a piston filling system with which you can fill up almost 2 ml of ink. A well-sealing screw cap ensures that the pen always writes at every start and gives a nice flowing ink line. The steel nib is available in different line widths from EF to Stub and writes excellently.

 Each Diamond comes with a wrench and silicone grease to dismantle and clean the pen easily. It is not necessary every time, but it is useful if you have used some characterful ink.
 
 With the Diamond 580/AL/ALR you can unscrew the grip with the nib and clean it or replace it with another nib. Nibs for the Diamond can also be purchased separately.
