Not for Toyota/Scion
Lots of clips to choose from but none fit the car (06 Scion) I was working on. Grabbed one that was close, bent, folded and cut it until it fit. It works, but it was 100% a different clip when I was done.

Must have
Size: 200 PCS
If you have machines, you have to have these available. The old ones are reusable, most of the time, but when they aren't, you have these. They are of the same material and quality as OEM. Same size, of course, and the few I have used look factory.
