Pimp your cardboard box! Before going crazy with gifts this holiday season, remember that kids tend to have more fun with the box a toy came in than the toy itself. With a little imagination, a box can be converted into a car, plane, or train stand, but with Rolobox, it's reality. For $13, this set of reusable wheels and brackets can be attached to any box and transform it into a mode of transportation. With chunky nuts and bolts, the hardware is perfectly sized for preschoolers to use on their own, though some adult help may speed up the process!
