The David Oscarson Trellis Collection employs the wondrous arts of guilloche and hard enamel to capture the lovely curling tendrils of climbing plants.  A superb demonstration of Old World craftsmanship, each Trellis writing instrument involves multiple operations of engraving to realize the "leaf and bud" motifs, whose beauty is brought out by the application of translucent and opalescent enamels, and yellow gold and rhodium vermeil. The David Oscarson Trellis Collection is produced in five color variations, each being limited to an edition of 88 pieces.  Fountain pens feature iridium-tipped 18K gold nibs with ebonite feeders; the filling system is meticulously sealed with a series of O-rings, and can employ a cartridge, converter or eyedropper fills.
