The 15cm Aluminum Ruler from Midori is a cult favourite and another winner of the Good Design Awards (2013)
This 15 cm ruler is made from lightweight yet strong aluminium. It is laser engraved so that the numbers do not disappear over time and use.
With an aluminium edge, it can be used with a knife cutter. The slanted shape makes it easy to pick up and hold.
Also available in an aluminium / wood version.
