They’re okay
Color: 40pcs
These fender clips are just okay. They fit reasonably well and did the job for a quick fix, but the quality isn’t the best. Some of them felt a bit flimsy, and a few broke during installation. If you’re in a pinch and need a temporary or budget-friendly option, these will work. Just don’t expect OEM-level durability. Decent for the price, but not great.

Quick and easy part to install
Color: 40pcs
My wife accidentally hit a parking curb and popped the bumper cover of her car. The flexing caused some of the clips to break. The bumper sprang back, but the clips just fell out. Basically, they sacrificed themselves. These new clips fit perfectly and the bumper is ready for action. Keep some in your glovebox, you'll be glad you did.
