This AWE Enterprises HO brass 2 - bay open hopper is a great addition to your collection. When using it, simply place it on your model railroad track. It has sprung trucks which help it move smoothly. Since there are no couplers, you may need to attach your own if you want to connect it to other cars. As for maintenance, because it's brass and unpainted with little tarnish, you can use a soft, dry cloth to gently clean it every now and then to keep it looking good. Store it in the original box and foam when not in use to protect it from damage. When shipping, we've packed it carefully, but once you receive it, handle it gently as it's a fragile item. And if you're not satisfied with your purchase, let us know within 30 days for a no - questions - asked refund (you'll just need to cover the return shipping unless the item arrived damaged).
