I use this to collate groups of thirty-five pages that go out to the teachers at my school. I take in a box with stacks of flyers bound with this binder clip and the secretary can quickly and easily place a bound stack in each teachers mail slot to distribute school PTO flyers.
I have used these to hold down the plastic sheeting over my gardens. Stayed all year though snow rain and sun. Also could keep a grill cover from blowing away. Like I said goes beyond regular office use.
