Thank you for viewing. This is a set of 19mm aluminum bearing rollers with plastic rings for Mini 4WD. These are genuine Tamiya parts, not aftermarket products. I am selling these to clear out my inventory. They are used and have scratches and dirt. The screws are not included, as they were only for the photo. The listing is for one pair (2 pieces) as shown in the image. I have confirmed that they spin, but they were removed from a car that was not used, so please understand that these are junk parts before purchasing. I am not responsible for any issues such as damage to the plastic rings or deformation of the rollers due to running. Recycled materials may be used for packaging. No returns accepted.
