What if you could mail someone a snowball? With our North Pole Snow card, you can! Just add 1/4 cup of water, and be prepared for a snowy surprise. Snow will grow to 100x its size (roughly the size of a snowball). This card is so much fun to send to kids, or to family and friends who live in warmer climates. L 4.5" x W 5.75" x H 0.25"
