Picked up this 40-piece set to replace missing/broken push-type retainers on my bumper/fender liner area. The assortment is a solid value—having extras on hand is way cheaper than buying a few at a time locally. The clips I used snapped in securely and held the panel tight without rattles. Tip: match the old clip’s size before installing (hole diameter + stem length). I tested a couple first to confirm fit and then finished the job. For basic trim/under-cover repairs, this is an easy, cost-effective kit to keep in the garage.

These fit perfectly! They are easy to install and very durable! I have no doubt that they are holding everything in place. They are also very easy to remove and do not break during removal, which is great.
