Thank you for viewing. This is a Mini 4WD mass damper set (black). It is a genuine Tamiya product, not an aftermarket part. I am selling this 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). These parts were removed from a car that was not in use, so please understand that they are junk parts before purchasing. Only the mass dampers are included; screws and other accessories are not included. Recycled materials may be used for packaging. Returns are not accepted.
