Cheerios snack mix from General Mills is now available in boxes of 12 single-serve pouches. The iconic ready-to-eat cereal forms the basis of a new snack mix that debuted earlier this year. Cheerios Snack Mix contains elements of other General Mills cereals, like Wheat and Corn Chex, as well as bread twists, pretzels and other components. The new package comprises 12 pouches of 1.65 ounces each, in a litho-printed paperboard carton with a U-shaped score on the front, a crash-lock base and a self-adhesive paper tab on the top closure.
