The cap and barrel are decorated with Gothic arches and a rosette on the cap is an homage to the rose window of Notre-Dame. The end of the clip, which is shaped like the clapper of a bell, recalls the bell ringer Quasimodo and the bells of Notre-Dame. The cone of the Limited Edition 1831 is decorated with an engraved trefoil frieze, which is also part of the architecture of Notre-Dame. The shape of the cone, with a single chain link at the end, recalls the posts to which Quasimodo was chained. The yellow lacquer on the bottom of the cone is the reference to the yellow prisoners passport given to Jean Valjean. An engraving of the line ‘Chaque homme dans sa nuit s’en va vers sa lumière’ from Les Contemplations on the cap top symbolizes the idea of redemption. The cap top is also crowned by the Montblanc emblem in mother-of-pearl. In honour of the year of the publication of Hugo’s novel Notre-Dame de Paris (1831), the edition is limited to 1,831 pieces.
