I am not familiar with this product, but I believe it is a part for an old radio-controlled model car. It appears to be unopened, but please check the parts in the images. It says 3018 COX/KYOSHO SKID PLATE. The bag has dirt and scratches due to aging. I have not opened the parts, so I do not know their condition. This is a vintage item, so please consider purchasing only if you understand this. First, please comment.
