The Santa Letter Kit includes everything you need to create some Christmas magic! Includes 3 fill-in style letters to Santa (perfect for children of all ages) with kraft envelopes, 3 "North Pole Post" cards with red envelopes, 3 official Santa Seals, 1 brass bell, and 1 packet of expanding "snow." Just add water, and snow expands to 100x its size for a fun way to leave traces of the big guy on Christmas morning.
