Nik-L-Nip is a brand of confectionery created by Vinny Cavallo in the early 20th century.
It comes in a variety of fruit flavors, marketed by Tootsie Roll Industries.
The Nik-L-Nip brand name is a combination of the original cost (a nickel, $0.05) and the candy's resemblance to miniatures of alcohol, known in some regions as "nips".
The name may also come from a preferred method of opening the wax bottles, which is to nip (bite) the top off.
[1] Once the top of the small, bottle-shaped wax containers has been bitten off, one can drink the fruit-flavored syrup inside.
