This HO brass box car is a great addition to your collection. When you first get it, take it out of the box carefully. Since there are no couplers installed, you can add your own if you want to connect it to other cars. Just make sure to choose the right type for a good fit. As for maintenance, keep it in a dry place to prevent any rust on the metal wheels. You can use a soft cloth to gently clean the brass parts every now and then. If you're shipping it back for a return, follow the same high - quality packing we used to ensure it arrives safely. Enjoy your model and have fun setting up your train layout!
