Review on Universal Roof Headliner Repair Buttons - Set of 60 Rivets, Automotive Car Flannelette Fixing, with Installation Tool - Fits All Cars by Derrick Milkie

I was thrilled when I ordered them and the product looked great when it arrived. I had a small area of sagging lining on the rear window so I decided to try this. It's easy to understand - take the ring, unscrew and twist it, and then put on the gray cap, but. large but the screw only goes halfway and then hits the metal of the roof :( So if you can screw in a full screw that should make it flush to click on the round gray cover I had to unscrew it and it left a hole in the liner - being smart I was able to fix the hole so you can't see it but this product is awful and as you will see Michael Myers turns the corner RUN RUN RUN away from this product and NOT TO BUY!
