Using your HO scale brass box car is easy. You can place it on your model train tracks and couple it with other cars. To open the doors, gently pull them apart. When handling the car, be careful not to put too much pressure on the bent door track. For maintenance, you can use a soft cloth to gently clean the car's surface. Avoid using harsh chemicals as they may damage the paint and brass. Store the car in a dry and cool place, preferably in its original box to protect it from dust and scratches. If you have any questions during use, don't hesitate to contact us.
