Heavy-duty staple removers work best for removing staples from cardboard, wooden crates, and plastic boxes. They are mainly made up of metals and are strong enough for removing larger staples.

There are different types of staple removers based on their design. Stapler removers comprise of blades, torsions springs, pin axles, and plastic grips. The teeth-like staple remover is the most common in the market. You only slide the teeth like fangs under the bent part of the staples to straighten them out. Then you slide the teeth under the main bar of the staple to pull it out. It takes little time for the entire process of staple removal.
