I have been using clips for quite a number of years. There is nothing like them to hold thick stacks of papers. Paperclips are always getting caught or fallaing off.
I use this product for many things at home work school and even used it for paperwork in my car. It's great--there are many moments where I say Oh Yeah I can use one of my binder clips for this. It keeps things organized and works so much better than rubber bands that break all the time.
I actually used these clips to hold together glued cloth as a clamp. I was making miniture sand bags for my grandsons 1/24 scale RC tank. I filled the bags with sand and then applied glue to the opening and used thes clips to hold the opening closed till the glue set. Worked great.
