Thank you for viewing. This is a set of lightweight 19mm all-aluminum bearing rollers for Mini 4WD. These are genuine Tamiya parts, not aftermarket products. I am selling these to clear out my inventory. They are used, so there is some discoloration, scratches, and dirt. The screws are not included, as they were only for the photo. This listing is for one pair, 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.
