Paper Clips
Recycle your paper clips or reuse the ones you have. Enough paper clips are produced each year to hand every person in the world at least three. For every 100,000 paper clips produced, only 20,000 are used to hold paper together. The rest aren't being used.
Additional Information:
Offices that receive a lot of paperwork every day may have more paperclips, rubber bands or binder clips than they need and might be willing to share. Ask around!
