Binder clips last two seasons before they rust through and break.
I ordered some, as I didn't want metal pieces I missed all over the yard.
These work okay and have lasted a few years but I don't think we have half of those plastic tips anymore. At least they're bright colored lol.
Those are okay if you clamp something and leave it, but we move plexiglass panels around sometimes daily to block wind for the growout pens. So the on off, on off, those plastic things pop off, and you put them back on. A bit tedious.
