Mini 4WD Lightweight 2-Stage Aluminum Rollers, 12mm-13mm. These are not anodized, but genuine Tamiya parts. As you can see in the photos, there is almost no wear and tear. However, since they have been opened, I'm listing them as having no noticeable scratches or stains. Please check the photos carefully. These are green. Also, these are used, but I will include the bearing rollers and accessories as a set, though please consider them as extras. Please consider this before purchasing. I am selling these because I have retired from Mini 4WD. If you have any questions, I can add more photos. Please understand that I will not accept cancellations after purchase.
