the compact 'rollbe' measuring tool is no larger than a coin

the design of the ‘rollbe’ ruler by toronto-based the work of mind inc allows it to be rolled from point to point taking an accurate measurement in the metric or imperial system. designers, carpenters, fashion designers, sewers, architects and many other professionals draft specific layouts and templates where measuring curves and design details is necessary. its two smallest sizes, 4 inches and 10 cm are both comparable to the size of a coin making it comfortable to carry in a pocket or key chain.
