Keep reusing as much as possible, including fasteners. Reusing is saving money and reducing effects of Climate Change.

I have been using these fasteners for many years.  They came from folders of outputs submitted by students.

These fasteners are used for filing, grouping papers, sheets, reports. The papers beside the box are survey sheets for my students' research.  Sheets will be grouped according to section using fasteners.  Once done with research, fasteners will be kept again and the sheets will be given to parents who use paper to ignite fire for cooking.
