Review on Niteguy 70pcs Car Roof Headliner Repair Button Kit - Auto Roof Snap Rivets Retainer Set for Car Roof Flannelette Fixation - Includes Installation Tool - Suitable for All Cars (Light Grey Grid) by Joshua Reid

I had a gray mesh color that almost matched my interior accent. I don't know what happens to the screws over time? Can foam rubber become detached or rust due to damage? BUT as long as they do their job. Pretty easy to install using just your eyes for distance. "Near enough". If you have a huge headliner like my vans, do yourself a favor and don't rush to get them all done in one sitting. I made about a dozen, then broke, came back with a fresh look and kept going! My headliner wasn't completely loose, it was just starting out so I knew the situation straight away. If the headliner is coming loose from the top of the windshield, get some T-pins from Walmart to fix it if glue isn't your thing. (These knobs are too big, I don't think they will work in that area.) These knobs/screws don't hit "my" metal roof through the back of the headliner! My van is too old to spend hundreds of dollars on a sagging headliner and it is very difficult to replace it yourself without the help of professionals. -) No updates means they are good and long lasting!
