Good value. Not OEM
These clips don't fit perfectly for my honda civic. They also aren't as strong or durable as the OEM clips. The plastic is harder so they crack and fall out instead of giving if you're driving on bumpy roads. However, having a bunch of these clips in the back so I don't have to look up part numbers and order a bunch of different things is great. It does the trick and is way better than having your trim fall off. It's a quick and dirty fix... but hey, if you do DIY repairs and aren't going to the shop for it, it's probably what you are looking for.

Clips are awesome, tools kinda crappy
The assortment is on point with OE supplied retainers, the ones with metal especially are just like the originals offered by Honda.
