Rollova Digital Rolling Ruler
Rollova is a compact measuring tool designed to measure just about anything and easily fit inside your pocket. Instead of relying on a typical oversized ruler, this little tool can measure both straight and curved lines by rolling from point to point. It can measure a wide range of surfaces, objects, and materials with a single motion. With one easy roll at a time, the sleek device provides you with an accurate measurement on its OLED screen. It displays the measurement length in centimeters, inches decimal, or inches fractional as you roll it across flat, or curved surfaces. How cool is that? watch the video below
