TWSBI Diamond Mini Clear Fountain Pen

The TWSBI Diamond Mini is a completely disassemblable pocket-size fountain pen with a traditional piston system. The flexible steel nib allows the line thickness to be controlled through pressure. Another special feature of the pen is the faceted, transparent body that gives the writing instrument its name. The filling level can be seen at all times. The handle and lid are transparent as well.
