A great nostalgic candy. These are individually wrapped chewy peanut caramels. Squirrel Nut Zippers, the vanilla nut caramel variety, were developed in the mid-1920s to complement the chocolate variety. Squirrel Nut Caramels were originally made by the Squirrel Brand Company, and are now part of Necco. A public park named Squirrel Brand Park is now located at the former site of their factory.
