Durable and well fitting
Durable and well fitting. I drive a Honda Accord 2014 and when the under engine covers started falling off I used these to replace the ones that came off. They work well and the prying tool made replacing the retainers easier.

This product has many different sizes making it easy to fit clips in other parts of the car.
I was working on my grandson Honda. It was missing the plastic clips to hold the fender liners in place. This worked great and helped hold the fender in place. I used the puller tool many times on other plastic parts on the car.
