parts VALID. Really durable and better than I thought. I haven't been able to get them on the center caps of my rims, they had to stick one on my 2006 Mustang's rear GT badge. It was slightly smaller than what I measured with calipers to determine coverage, but the difference in size isn't that noticeable. They are made of very durable aluminum with polished, shiny emblems. I wiped the area with rubbing alcohol and the decals have stuck in place. The product appeared to have a matte finish at first, but luckily it had an ESD shield on the front. They are beautiful, shiny, clean and look very pretty in any practical application. If you're looking for GOOD QUALITY stickers like these, feel free to grab a set. You will not be disappointed.
