Using this tank car is simple. Just place it on your HO scale model railroad track. When handling, be gentle as it's a fragile brass model. To keep it in good condition, store it in its original box and foam when not in use. Avoid exposing it to extreme temperatures or humidity, as this can cause more tarnish. If you need to clean it, use a soft, dry cloth. If you're not satisfied with your purchase, let us know within 30 days and we'll refund your money, but you'll be responsible for return shipping unless the item arrived damaged.
