Using these HO scale brass covered hoppers is easy. Just place them on your model railroad tracks and they're ready to roll. When handling, hold them gently as they're fragile. Keep them away from sharp objects to avoid scratches on the custom paint and weathering. For maintenance, use a soft, dry cloth to dust them off occasionally. Don't use any harsh chemicals or abrasive cleaners as they can damage the finish. Store them in their Reboxx box and foam when not in use to protect them from dust and potential damage. If you have any issues with the couplers or trucks, check if they're loose and gently tighten them if needed. Enjoy your custom - painted and weathered hoppers on your model railroad!
