Akin to Legos, Magna-Tiles are great for kids (or adults) who like to build and experiment. The company’s first ever advent calendar packs 34 holiday-themed magna-tiles, including 10 decorated magnetic squares, three decorated isosceles triangles and a microChassis that actually rides the track on the back cover of the package. Yes, Santa and conductor figurines are included as well, so you can build a complete holiday train scene by the end of your time with this calendar. — Valentina Palladino, Deputy Editor
