Sea otters spend 48% of their time grooming their dense fur and that's not for vanity's sake. Otters need to keep their fur clean of debris so their natural fur oils can trap in heat and repel water. Unlike many marine animals, sea otters don't have a thick layer of blubber to protect them from the frigid temperatures of the waters in which they live. But also...they DO look good, don't they?? This sweet pair of perfectly coiffed otters is 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.
