This is a Toyco light-up Dekotora (decorated truck) trailer radio control truck, "Kairyu-oh" (Sea Dragon King). Operation has been confirmed. Total length is approximately 65 cm. Width is approximately 11 cm. Height is approximately 20 cm. The trailer bed is from the same series, the "Ryuoh-maru" (Dragon Phoenix Circle). Please note that it differs from the image on the box. The casters on the trailer bed's receiving part have been removed. While the separation can be done smoothly with the casters attached, it puts a strain on the truck when driving, making it unable to run. I can attach them and ship it if you wish, but I would prefer to ship it without them. It's a 3-channel radio control, and the trailer can be detached. The light bulbs on the trailer bed flash when batteries are inserted. It's an old item, so there is some dirt and discoloration. There is rust in the battery box. Batteries are not included. No price reduction. I will not respond to comments asking for a discount.
