Overlapping Ruler / Ruler

Overlapping Ruler

The creative overlapping ruler features its detachability into three separate ones. Materials originally used in one unnecessarily big ruler can now be made into three handy ones. Three people need originally three rulers but now only one ruler is needed. All this helps to save resources as well as the room used for placing rulers.
