The Swingline Low Force 1-Hole Punch is built for durability, with strong, all-metal construction. It easily punches a precise ¼? hole through as many as 20 sheets of paper. A slim handle and ergonomic low force plier design makes punching easier on your hands. This powerful punch requires less manual force to operate than traditional hand-held punches. A built-in, hinged compartment contains scraps to reduce mess: simply open it over a waste basket to empty it. Swingline backs this high-quality punch with a limited 1-year warranty.
