Using this caboose is easy. You can simply place it on your HO scale train track to complete your train set. When handling the caboose, be gentle as it's a fragile item, especially since it's made of brass. For maintenance, you can use a soft cloth to clean the surface gently. Avoid using harsh chemicals as they might damage the brass or the paint. If you notice the tarnish getting worse, you can use a mild brass cleaner, but test it on a small, hidden area first. When storing, keep it in a dry place away from direct sunlight to prevent further tarnishing. Also, make sure to keep it in its original box and foam to protect it from bumps and scratches.
