Rollbe Compact Measuring Tool
Rollbe is a super compact measuring tool designed to measure just about anything. The stainless steel ruler easily fits in your pocket and can measure both straight and curved lines by rolling from point to point. Designed both in the Metric and the Imperial system, the little tool is available in two different sizes: 4 inch (10 cm) or 8 inch (20 cm). To use it, simply place the start mark on the starting point of the surface or line you want to measure then roll and count full rotations, then add remaining units. Each Rollbe features a brass handle for steady use, and comes a leather chain pouch. watch the video below
