Even leaving aside the political and humor aspects of this set, these cards are interesting simply due to the unusual plastic material they are made from; unlike cardboard or more rigid plastics, these can bend nearly in half without apparent damage and seem almost indestructible with ordinary handling. It's similar to those plastic fiber shipping envelopes that I hate, but thicker (maybe 2/3rds of thin card stock) and with a glossy finish. If all cards were made of this stuff, they'd be far easier/cheaper to package and ship.
