TWSBI Diamond Mini

There are 7 products.

The TWSBI Diamond Mini is a shorter, pocket-sized version of the Diamond 580 fountain pen. The barrel is shorter than the standard Diamond series pens but the cap can be posted by screwing onto the end of the barrel to create a full-size pen.  Due to the piston filling mechanism the TWSBI Mini has a big ink capacity for a small pen.  It can be filled from any fountain pen ink bottle, but for clean and easy refilling, try a TWSBI Diamond 50 Ink Bottle, which is specially designed for refilling TWSBI Diamond fountain pens.  A wide range of spare nibs are available including italic nibs.

Note that the nib section of the Diamond Mini is not compatible with other TWSBI fountain pens (eg. Diamond 540, Diamond 580, Vac 700 and Micarta).
