Ancient Persian Deck of Cards Bridge sized playing cards The cards are plastic coated Superlux Cambric card stock (more specifically they have an Aqueous coating). This offers a better feel to the touch and is resistant to bending and scratches, but unlike purer plastic, it can be torn by hand if enough pressure is applied. The cards are washable. We have personally tested this by marking one with a pen and then washing it out. Washing did not ruin the card or smudge the print.
