Thank you for viewing. This is a set of lightweight 13mm all-aluminum bearing rollers (red) for Mini 4WD. These are genuine Tamiya parts, not aftermarket. I am selling these to clear out my inventory. They are used, so there is some color fading, scratches, and dirt. The screws are not included, as they were only for the photo. The listing is for 2 pairs (4 pieces) as shown in the images. 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. Recycled materials may be used for packaging. No returns accepted.
