This is a set of 30 Tamiya genuine carbon fiber plates. I retired several years ago, so I think there are many carbon fiber plates that are a bit old. The top left four plates are 3mm carbon fiber, the next four plates and the next row of three are 2mm carbon fiber, and the rest are 1.5mm carbon fiber. The last two plates in the photo have been processed, and some other parts have also been used. Some of these are unused, but they have been opened, so I've marked them as slightly dirty. Please check the condition carefully in the photos. Please consider this after understanding the above. I'm selling these because I've retired from Mini 4WD. If you have any concerns, I will add more photos, but I will not accept cancellations after purchase, so please understand.
