These U.S. Hobbies pulpwood flatcars are great for your model train collection. Since they don't come with trucks or couplers, you'll need to add those on your own to get them running on the tracks. When handling them, be gentle because they're fragile, especially being made of brass. Store them in a dry place to prevent further tarnishing. If you're not happy with your purchase, just let us know within 30 days and we'll refund you, but you'll have to pay for return shipping unless the item arrives damaged. And remember, we pack them really well to make sure they reach you safely.
