Using this HO brass Oriental Limited water car auxiliary tender is straightforward. Just couple it with your compatible train set using the Kadee couplers. When handling, be careful of the minor bends in the top railings to avoid further damage. Store it in the original box and foam when not in use to protect it. For maintenance, you can gently clean the brass parts to prevent any further tarnish. Since it's an unpainted model, avoid using harsh chemicals that might damage the surface. When shipping, take note of the shipping rules and rates. If you're in the USA, you can get free shipping for purchases over $199. International buyers need to pay for import - related costs. And if you're not satisfied, you can return it within 30 days, but you'll be responsible for return shipping unless the item arrives damaged.
