Usually, most of the paper clips I get from clients get pitched as I am going through their stuff.  Some of them are rusty since I think they came over on the Mayflower.  Others are so small that they are useless other than "clipping" one piece of paper.  I also hate the ones with the "serrated" edges that lock on to paper like vise grips.  I only use the smooth jumbo paper clips, anything else is useless to me.  But in the future, instead of filling the local landfill I'll start throwing them in the "Jim" box and send them to you once the box is full 😉
