3D playing cards feature 54 unique 3D images, a different fully 3D Shark image for each card. To block out all light from passing through the otherwise transparent lens and give the pips a pleasing metallic shimmer, our cards are constructed from a metallic foil core sandwiched between a thin optical lens for high quality 3D and a soft touch PET laminate for smooth shuffling. All card images are printed in cutting edge lenticular 3D, giving you over an inch of depth in the thickness of a standard playing card. All without the need for special equipment or viewing techniques.
