    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.

    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.
