These are sturdy replacements for your door panel clips if any should tear off while removing the panel to undertake repairs. The texture and holes help create a mechanical bond between the glue and the clip. I went ahead and reinforced the bond by adding a layer of fiberglass over the clip's pad. I have had my door panel off several times and have not lost any clip bases. However, I have had to replace a few of the cone shaped inserts. Expect quality from 3DBimmer!
