Length can be measured in both centimeters and inches
The ruler is in centimeters and inches. The edges are deburred but there is a little bit of the edge.The clasp is made of stainless steel. The ruler portion is a combination of centimeter, 0-36 cm and inches (0-14 inch).Additionally, all markings are printed inside the resin instead of surface printing, so the scale will not fade after prolonged use.
