This is a set of transmission and related parts made by RC4WD. Purchasing new from the official website would cost approximately 16,000 yen, excluding shipping. The grease used is brown, high-viscosity grease sold at home improvement stores. Please note that it is not genuine RC4WD grease. The defects are a chipped part on the lower right screw guide of the transmission section and stripped threads in the upper left screw hole. There are no problems with running, but if used without maintenance, grease will seep out. Please consider this as a junk item, as there are small scratches that are difficult to see in the photos. If you have any questions or would like additional photos, please feel free to ask in the comments.
