Wax bottle candy was created in the early 1900s and is officially known as Nik-L-Nip. It is now marketed by Tootsie Roll Industries.
The brand name (Nik-L-Nip) is a combination of the original cost of a nickel and the preferred way to open the wax bottle which was to bite off the top (Nip). Once the top of the small, bottle-shaped wax containers has been bitten off, one can drink the fruit-flavored syrup inside. Afterward the wax can be chewed like gum.
Although the wax bottles are food-grade and non-toxic, they are not meant to be eaten. The juice inside the wax bottles comes in a variety of flavors.
