This vehicle has been maintained by an amateur so that you can enjoy it for a long time. Of course, the operation has been confirmed. My operation check means confirming that it runs properly. It's not just "it moved when I put in batteries, so it's good!" The Red Bear has no noticeable scratches or dirt, but the freight cars have some scratches and dirt. To ensure a smooth transaction for both parties, please feel free to comment if you have any concerns or would like additional images. Seriously, please refrain from interacting if you are overly concerned about details. I am also selling other items. If you would like to purchase multiple items, please use the "request combined purchase" function to consult with me. I will almost always accept requests, except for manual entry of the desired price. Please also take a look at my profile. The following is for those who are interested. Here's the work that was done: ★ Removal and cleaning of dust, hair, etc. from the wheels and motor unit of the powered car. There may be some areas that couldn't be completely cleaned. ★ Independent maintenance of the motor. Restored the motor to its original condition. Since it has not been replaced with an aftermarket motor, it may be possible to request repairs from the manufacturer. They will not accept modified items. ★ Cleaning of the exterior using various cleaners. The above is the maintenance content. I have not done anything more than this. I hope we have a good relationship. m(_ _)m
