Made under license to HBO, Montegrappa’s new Game of Thrones pen, Winter is Here, pays homage to the mysterious forces from north of The Wall.

Using the ancient jeweller’s art of lost wax casting, Montegrappa has created half pen, half objet d’art.

Three-dimensional effigies of the Night King andWhite Walker form a sterling silver superstructure that encases a body of shiny lines celluloid. The figure of Viserion wrapsaround the cap, and the dragons head witha tongueof ice coming out ofits mouth acts as an innovativepocket clip. Enamelled, crystal blue flames encirclethe base of the cap, while semi-precious apatite stonesemulate the cold, mysterious eyes unique to beings ofthe North.

Limited to just 300 pieces, the Winter is Hererollerball arrives in a deluxe, black lacquer wooden case with a custom booklet.
