20-sheet electric stapler features extra-wide lead-in & line-of-sight markings that help you intuitively position papers to place staples exactly where you need. Push-button staple loading allows you to easily reload staples for fast refills. Nonskid base prevents it from sliding on smooth surfaces to stay secure when stapling. Simply plug this stapler into an outlet for desktop use, or install four AA batteries (sold separately) for convenient portability. Electric stapler is designed for use with standard-size staples.
