This professional, 3-in-1 Digital Tape Measure makes measuring faster, easier and much more precise. It lets you take accurate measurements in 3 different ways. First, you can use the retractable nylon string that will bend around objects. Second, you can use the built-in roller and simply roll it across the surface. Third, you can measure the distance by simply pointing the laser beam. The large, easy-to-read LED display on top will show you the exact measurements. Measuring tape itself is 10 feet long. Req. 4 "AAA" batteries (sold separately). Plastic and metal. Approx. 3 1/3"Sq.
