Swingline's Light Duty Standard Stapler is an ideal choice for your basic stapling needs. While generally designed for desktop use, this stapler is also great for tacking and pinning. Helpful, low-staple indicator alerts you when it's time for a refill. A pack of 2 staplers allows for convenient placement throughout the office. This stapler firmly secures up to 20 sheets of paper and works best with standard size Swingline S.F. 4 Premium Staples. Standard staples have ¼” length legs. For tacking paper to a bulletin board or other vertical surface, simply lift the top of the stapler and you're ready to tack. This stapler also easily produces pointed staples for temporarily pinning paper: just reverse the anvil by pushing and rotating the adjustable knob at the bottom of the stapler and press for a temporary staple you can easily remove..
