Walk the snow drifts with Precious Polar Bear Cubs Personal Checks. These checks feature wintery white bears with their mothers, playing and sleeping in the snow. Cubs are born about the size of a rat and weigh about a pound. Polar bear cubs often starve; only about 30% survive past their third birthday. Precious Polar Bear Cubs Personal Checks are available in single and duplicate check format. Matching address labels and a coordinating checkbook cover are also available.
