2 DECK BOX SET BOX IS BLACK AND SAME SHAPE AS METAL CASES EMERALD METAL CASE AND EMERALD DECK ICE BLUE METAL CASE AND ICE BLUE DECK VXD Gaming brings you the London Diffractor. Designed by VXD Gaming and Lance T Miller and produced by Vrijdag Premium Printing, the London Diffractor decks use the patented printing technology developed by VXD Gaming (US. Patent. No. 8,777,225), which combines a standard layer of ink printing, as found on normal playing cards, with an additional hot-stamped layer of transparent holographics, of the type typically only found on passports and other ID documents. This combination produces an entirely unique look within the playing cards industry and presents new possibilities for design expression and sets a new bar for luxuriousness. The result is a mesmerizing combination of holographics and ink, lighting up at different angles and in different lighting conditions and producing a combined artwork which tells a story of the heritage of London. Our tip: For best effect, we recommend viewing under a single bright light source such as a halogen spotlight, with ambient lighting around (such as daylight) cut to a minimum. Casino table lighting conditions are ideal, for instance.
