The Everlasting Gobstopper is both a fictional brand of candy, as well as an actual confection named after the fictional product. The fictional Everlasting Gobstopper is a candy that not only can never be finished, but never even gets smaller. It is implied that they may also be indestructible. Wonka explained that they were 'for children with very little pocket money'. According to Slugworth in the 1971 film, the Everlasting Gobstopper would entirely ruin his business. A product called Everlasting Gobstoppers was introduced in 1976 by the Chicago candy company Breaker Confections, which had licensed the 'Willy Wonka' name in 1971 so that it could be used as a merchandising tie-in for Willy Wonka and the Chocolate Factory. The Willy Wonka Candy Company brand is now owned by Nestle, and made in Itasca, Illinois. The jawbreaker is composed of several discrete layers to mirror the color-changing effect from the book.
