But how will Santa get inside?" Not everyone has a chimney, after all. Reassure children that Santa can still visit with his magic key. Comes with sentiment card which reads: "If a house has no chimney for Santa to come in, or if the chimney's too small (since Santa's not thin!) There's nothing to worry about because Santa can see how to get inside if you leave him this key!" Mini key with Santa head is about 1 3/4" long.
