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.

Great
Had a splash guard come off my Honda and these were perfect and so easy to put the splash guard back on. They are very durable and good quality. I recommend these!

Fit as described
Used to install an inner fender liner. Seem a little more fragile than OEM, but suitable for the intended use and much less expensive.
