Our playful Mail a Snowball Cards guarantee a white Christmas for all! Attached to each holly-red 4¼"x5½" card is a little packet of "Santa-approved official North Pole snow"—a nontoxic, polymer/glitter-blend powder that, when mixed with water, expands 100 times, turning into a fluffy pile of "snow"! The amazing substance is fun to play with and merrily decorates trees, holiday villages, or other Yuletide features. Each card includes enough snow for one "snowball" and comes with instructions for snow making. (To reuse, simply spread the snow on a plastic surface and allow it 48 hours to dehydrate and return to powder form.) What fun for young and young-at-heart friends…especially those who live in warm climates! Set of 2.
