Six-Pack Cereal Boxes.  Six individual cereal puzzles make up this selection of childhood favorites – Lucky Charms, Cheerios, Honey Nut Cheerios, Cinnamon Toast Crunch, Cocoa Puffs and Trix. Each 100-piece puzzle will have a finished size of 9” x 7” (and, of course, the pieces will be a little smaller than our usual piece size).
