Using this HOn3 brass business car model is easy. You can simply display it on a shelf to show off its beautiful details. When handling it, make sure to hold it gently as it's a fragile item. Keep it away from rough surfaces to avoid scratches. For maintenance, use a soft, dry cloth to dust it regularly. Don't use any harsh chemicals or abrasive materials on it. Store it in the original box and foam when not in use to protect it from damage. If you need to move it, wrap it in bubble wrap for extra protection. Also, be careful when dealing with the spare parts, as they are small and can be easily lost.
