Thank you for viewing. This is a Mini 4WD mass damper set (silver). It is a genuine Tamiya product, not an aftermarket part. I am selling it to clear out my inventory. It has been used, so there are scratches and dirt. As shown in the images, this is a set of 1 pair (2 pieces). Since it was removed from a car that was not in use, please understand that it is a junk part before purchasing. Mass dampers only, screws and other accessories are not included. Recycled materials may be used for packaging. Returns are not accepted.
