The TWSBI Diamond 580 comes with a benchmark piston ink-filling mechanism and has all detachable parts. The clear demonstrator barrel allows you to see your ink color and remaining ink level. It has a clear grip section and screw-cap. It comes with a stainless steel nib and is presented in a modern clear display case. The idea behind the TWSBI Diamond 580 was to go back to basics and capture the simplicity and elegance of traditional writing instruments.
