Combos, officially called Combos Snacks, invented in the mid 1970s, are a snack food created and distributed by Mars Incorporated.

Production
Combos are produced by forming a soft bread-like dough, which is hollowed out into a tube-shaped form. A cutter slices the dough into bite-sized lengths. The snacks are then baked, cooled, and filled with the appropriate filling.
