ONE-OF-A-KIND patented deck of playing cards, featuring security-type transparent holographic. Vegas Classic = 499 Units, Vegas Gold = 499 Units, Vegas Gold Metal = 499 Units, Vegas Ultraviolet = 499 Units, Vegas Ultraviolet Metal = 499 Units THE PATENTED PART: Diffractor Playing Cards incorporate transparent holographics that are normally only seen on security and identity documents, such as your passport or drivers licence. The concept behind the technology allows the addition of a further layer of eye-catching custom holographic artwork over and above the standard playing card ink artwork, via carefully aligned and detailed transparent holographic foils, stamped (with heat and pressure) into the card front and back faces. The technology took over 8 years to bring to market from first conception, due to the complexities of combining the techniques used in security document printing with the traditional characteristics required of a deck of cards (such as texture, slip, snap and weight). All these key characteristics of a quality deck of cards have been painstakingly maintained and are un-compromised.
