De TWSBI Diamond 580 is made of transparent plastic, which provides a wonderful view on the inside of the pen, the piston mechanism and ink level. The AL version is equipped with a metal section and metal parts in the piston mechanism.

The pen’s character will change with every other color you fill it with.
The fountain pen details have a chrome trim and the plastic is facetted. 

For the adventurous people, the pen is easy to take apart for servicing or cleaning. A key and silicone grease are provided with the pen. Do this on your own risk.

TWSBI has been manufacturing pen parts form many companies and decided to use the gained experience by producing it’s own pens under the TWSBI brand.
