Wax lips are the common name of a candy product made of colored and flavored wax, molded to resemble a pair of over-sized red lips. The lips have a bite plate in the back; when the plate is held between the teeth, the wax lips cover the wearer's own lips, to comic effect. Invented by the American Candy Company in the early 20th century, they became a popular novelty in the United States for many decades, especially during the Halloween season. Their popularity among children can be attributed mainly to the comedy of wearing the lips; although they were intended to be used as a sort of chewing gum after the novelty of the gag wore off, the lips were often simply discarded rather than eaten.
There were also several similar molds used to make wax teeth, wax moustaches, wax finger nails, etc.
