Like the 2 pins per box mystery collections?
Right now, there's a Skyliner mystery collection called "There's Magic in the Air." 8 pins in the set, 2 pins per box, celebrating the debut of the Skyliner transportation vehicles. Mickey/Minnie, Snow White/Dwarfs, Hitchhiking Ghosts, Pooh & Piglet, Stitch, Pirates from Jail Scene, Belle/Beast, and one more that I can't recall off the top of my head.
