Staples seem insignificant. If we don't like their configuration, we rip them out and insert another. But all these tiny slivers of metal add up to big waste and make paper recycling more difficult. Turns out, metal staples are completely unnecessary for binding papers together. This handy staple-free stapler cuts a tiny flap in the corner of your paper, and folds it in on itself, tucked in a tiny paper pocket. Many different options available for around $7.99.
