Diamond Mini Fountain Pen Classic Black * TWSBI

 The TWSBI Diamond Mini is the pocket version of the 580. The transparent body is equipped with a piston filling system that allows you to fill up with approximately 1 ml of ink. A well-sealing screw cap ensures that the pen always writes at every start and gives a smooth ink line. You can post this pen by screwing the cap onto the back of the pen. The steel nib is available in various line widths from EF to Stub.

 Each Diamond Mini 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 580mini/AL 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.
