This collectible model is mainly for display. To use it, just find a nice spot in your room or display case to show it off. When handling, hold it gently to avoid any damage. As for maintenance, use a soft, dry cloth to dust it regularly. Keep it away from direct sunlight and high humidity to prevent further paint discoloring and damage. If you want to clean it more thoroughly, use a mild cleaning solution on a soft cloth, but test it on a small, hidden area first. Remember to always refer to the photos to see the current condition of the paint on both the tractor and the trailer.
