The Dialog is displayed in a wooden case made of beech. The ballpoint pen features a black wooden interior; it closes by miniature magnetic snaps, operates with a push button mechanism and is fitted with M 16 ballpoint refill.

The Dialog II Rollerball pens are fitted with LM66 rollerball refills.

The Dialog III twists to retract a platinized 14K gold nib. When twisted, closed a protective lens seals the retracted nib from damage and dirt.
