High quality replacement clips. Highly recommend.
I used these when replacing the headlight assemblies on my 2011 Honda CR-V. A few clips were already missing before I even started taking the bumper off, and of course a couple more didn’t survive the job.
These fit perfectly and snapped right in with no issues. If you’re missing clips or break some while doing a repair, these are a simple fix that gets everything secured again. Very good deal.
