This is 3 sticks of chewing gum that came from out of the Topps Michael Jackson trading card packs (2nd series) commercially available back in 1984.

Each pack came with a stick of gum, this is 3 different colored wrappers of that gum. I would NOT ADVISE eating this gum for any reason because it is over 30 years old. 

There may be some small flaws such as sugar stains or uneven foil bends but for the most part, gum is in very good condition
