Using the MierEdu Magnetic Car Puzzle Box is super easy. First, open the tin storage box and take out the magnetic pieces. You can place the box on a flat surface or stick the pieces on the fridge thanks to the magnetic function. Then, let your kids start mixing and matching the magnetic pieces to create different car designs according to their imagination. When they're done playing, just put all the pieces back into the tin box for storage. As for safety, make sure to keep the pieces away from very young children who might swallow them. To maintain the box and pieces, you can wipe them with a dry cloth. Avoid getting them wet as it may damage the magnetic function and the nature - based materials. Have fun playing!
