Actually not whales but the largest species in the dolphin family, orcas have long fascinated and mystified humans. They are incredibly smart animals and, even though they have no olfactory sense, their ability to echo-locate makes them fierce predators. Orcas even scare away white sharks! These playful and unique cards are professionally printed on 100% recycled paper (envelopes are 30% recycled content). Blank inside, so they may be used for a multitude of occasions. Design continues along the back for a panoramic illustration. Folded card size is 4.25" x 5.5", kraft envelope included.
