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.

Worked as expected, good assortment

Used these to replace missing/broken body panel fasteners and they fit as expected. The assortment covered what I needed without having to buy multiple packs.
Good quality for the price and handy to keep around if you work on vehicles.
