Based on a family tradition of an elf sent from Santa to watch over them at Christmas time, the illustrated story book The Elf on the Shelf was written and self?published in 2005 by a mother and daughter duo. The book tells a Christmas?themed story, written in rhyme that explains how Santa Claus knows who is naughty and who is nice; the best?selling book spawned an animated television show and an array of The Elf on the Shelf? holiday and children's products along with a follow?up book based on birthday traditions. Products include light and dark skin tone boy and girl scout elf soft figurines and book sets; elf clothing accessories such as couture puffer vests, capelets and game day jerseys; coordinating Tervis? tumblers with lids; birthday chair decoration kits and countdown games; Spanish language holiday books; plush pal night lights; Blu?Ray/DVD combo packs; DVDs and more. Bring the tradition home this holiday season.
