Heritage & Provenance
The story of this piece
Why it exists
In the 1940s Montblanc's Danish production developed a design language of its own, and the twelve-faceted No. 25 is its hallmark: a study in symmetry, structure, and refined modernism. The faceted form appeared principally in three colours — brown marble, green marble, and black — a focused exploration of material rather than mass variation.
Why it matters
The geometry does something flat barrels cannot: the brown marble pattern breaks differently across each of the twelve facets, warm beige and deep brown tones threaded with fine black veining, so that no two facets display the material in quite the same way. With the wide cap band, it is Art Deco design thinking carried into a writing instrument.
Why it is rare
Scandinavian production was modest beside the German factories, and the faceted models were never the common line. The Brown Marble execution elevates an already scarce design into a distinctly smaller surviving population — examples in this state of preservation appear only occasionally.
How it survived
Near Mint, with gentle wear on the cap ring and a couple of minor pits on the knob. The cap and knob imprints are deep and crisp, perfectly legible. The flexible 14C EF nib is a smooth writer, tested with light pressure; the push-knob system works fully and holds ink perfectly. Professionally serviced and in full writing order.
Taken together — the twelve-sided Danish form, the layered Brown Marble material, and honest Near Mint preservation — an enduring symbol of Montblanc's design excellence in its Art Deco chapter.

Rarity
E4 · Very Rare — on the Pen Essence Curation Scale
The twelve-faceted Danish No. 25 is already a scarce design; executed in the richly veined Brown Marble — one of only three colours in which the form principally appeared — surviving examples are increasingly difficult to find, and this configuration sits firmly in the very rare tier.
