Using this product is easy. Just take it out of the original box and foam packaging carefully. Since it doesn't have couplers, you'll need to attach them yourself if you want to connect it to other train models. When handling, be gentle as it's a fragile brass model. To maintain it, keep it in a dry place away from direct sunlight and humidity to prevent the plating from getting damaged. If you notice any dust, you can use a soft, dry cloth to wipe it clean. If you're shipping it back, make sure to follow the same high - quality packing standards we use to avoid any damage during transit. Remember, if you're not satisfied with your purchase, let us know within 30 days and we'll give you a full refund.
