A classic stainless steel 12" (30cm) ruler, backed with cork for a natural, non-slip grip for your measuring and cutting projects. Measure in Metric or Imperial - this ruler includes markings 30 centimetres with millimetres, and 12 inches with sixteenths marked over the first inch and eighths for the remaining inches. Each end has an extra º" beyond the first and last measurement so, if any damage occurs to the rulers ends, it should not affect the accuracy of your measurement. This sturdy steel will keep its crisp edge for years to come and the skid-proof cork backing keeps the ruler in place. Ideal for use with technical pens, pencils, hobby knives, and more.
