Arch Ruler
Curved Ruler

The 'Arch Ruler' is a curved measuring device. Its curve provides a dynamic balance allowing for effortless handling. The Arch Ruler shape also prevents smudging when drawing lines and is easy to locate on a crowded desk.  


Draw a clean straight line without stains or smudging. Just press down on the arch ruler and when you're done drawing let go. The arch ruler will spring back into it's natural position and you are left with a clean straight line.





As it is a curved ruler, it is not suitable for work which needs an accuracy in dimensions and precise drafting.
Please do not put it in a place that may be exposed to high temperature. There may be a risk of deformation.
Do not drop or use excessive force as it may be damaged.

Designer Comments: 

A curved ruler? Sure, it may sound a bit unrealistic. But it’s this kind of eccentric idea that makes the Arch Ruler more convenient and enjoyable than your old fashioned, traditional ruler.
