Using this HO scale brass caboose model is easy. You can simply add it to your model train setup. Just place it on the tracks with the Kadee Couplers attached to the rest of the train cars. As for maintenance, keep it in a dry place to prevent the brass from tarnishing. If it gets dirty, you can use a soft, dry cloth to gently wipe it clean. Avoid using any harsh chemicals as they may damage the paint or the metal parts. When moving or storing it, make sure to keep it in the original box and foam to protect it from any knocks or bumps. And remember, if you're not satisfied with your purchase, you can get a refund within 30 days, but you'll need to cover the return shipping unless the item arrives damaged.
