Using this O scale oil column is simple. Just place it on your model layout as you like. When handling, be gentle because it's a brass model and can be a bit fragile. For maintenance, keep it in a dry place to prevent any corrosion. If it gets dusty, use a soft brush to clean it. When shipping, we've packed it very well, but once you receive it, check for any damage right away. If you're not satisfied with your purchase, let us know within 30 days and we'll give you a refund, though you'll need to cover the return shipping if the item isn't damaged on arrival.
