Lightweight 13mm all-aluminum bearing rollers for Mini 4WD (black). These are genuine Tamiya parts, not aftermarket. Listed for sale due to inventory clearance. Used, so there is some fading, scratches, and dirt. Screws are not included, as they were for photography purposes. The listing is for 3 pairs (6 pieces) as shown in the images. Rotation has been confirmed, but these were removed from a car that was not in use, so please understand that these are junk parts before purchasing. Packaging may use recycled materials. No returns accepted.
