There's a ton of clips in this bag, and they fit the bumper I was installing easy enough. Can't complain. Nice that they included a tool as well, used it to help pull pieces when I was installing them incorrectly for a second. Word of advice to the manufacturer, maybe include instructions, it's not abundantly clear how to install these.
