Using this HO brass chair car model is a breeze. You can simply place it on your model train track to add a touch of authenticity to your layout. When handling the model, be gentle as it's a fragile item, especially the brass parts. For maintenance, use a soft, dry cloth to wipe off any dust. If you notice more tarnish over time, you can use a mild brass cleaner, but make sure to test it on a small, inconspicuous area first. Store it in its original box and foam when not in use to protect it from scratches and damage. When shipping or moving it, rely on the great packing we've provided to keep it safe. And if you're not happy with it, just let us know within 30 days for a hassle - free return.
