These model dump trucks are great for display. To use them, simply take them out of the box and place them on a flat surface. You can arrange them to create your own little construction scene. When handling the trucks, be gentle to avoid any damage to the delicate details. For storage, keep them in their original boxes or a dust - free container. If they get dirty, you can use a soft, dry cloth to gently wipe them clean. Don't use any harsh chemicals as they might damage the paint or the structure of the models.
