This HO scale brass caboose is a great addition to your model train collection. To use it, simply connect it to your train using the installed Kadee couplers. When handling, be gentle as it's a fragile item. Keep it away from sharp objects to avoid scratches. For maintenance, you can use a soft, dry cloth to wipe off any dust. If there's more tarnish over time, you can use a mild brass cleaner. Store it in a dry place to prevent further tarnishing. Remember, if you're not satisfied with your purchase, you can return it within 30 days for a full refund, though you'll be responsible for return shipping costs unless the item arrived damaged.
