A product called Everlasting Gobstopper 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 Nestlé, and made in Itasca, Illinois. The jawbreaker is composed of several discrete layers to mirror the color-changing effect from the book. The standard type has a chalky center similar to a SweeTart. A version with a chewy center is also available. They resemble the gobstopper from Charlie and the Chocolate Factory and its 2005 film adaptation far more than the ones in the 1971 film, as the 1971 version is a multi-colored, bumpy/spiky candy, and the ones in the book and 2005 film are round, single-colored spheres. Unlike the ones from the book and 2005, they are chewable once sucked long enough (Wonka says you would break your teeth if you tried to chew a gobstopper), and, unlike their fictional counterparts, they are not "everlasting". Seasonal variants, such as "Gobstopper Snowballs" and "Gobstopper Heartbreakers" are available during specific holidays. *** Description sourced from Wikipedia.
