Moving 3d greeting cards 8 pcs ass. Set of 8 different moving 3D cards, move the cards back and forth and the images come to life. The dogs move the head, ears and muzzle, the fish swim, the bear winks and I love you appears, the bees fly etc. The back of the card is pre-printed so you can put it in the mail in no time. Very nice to send as a birthday card.
