The Parker Duofold Mosaic International Fountain Pen. Created by building up a composite of different colored strips of cast acrylic.  These are diffusion bonded to form a solid block of material from which the component parts of the writing instrument are then precision machined and polished.  The finished pens are trimmed in platinum to create subtle accents that add to the artistic creativity of the design and result in a pen of immense beauty and sophistication. All Mosaics come from the Parker factory with 18K Medium nibs.
