There are usually graduations on the ruler to measure the length. Some rulers have a hole in the middle of a special shape such as a letter or a circle, which is convenient for users to draw pictures. The rulers used in different occasions have different requirements and standards. If the value is required to be more accurate, then higher technology is required, and it must be produced with the help of a machine. In addition to requiring accurate values, the second key point is the quality of the engraved values. Generally, a layer of protective film will be branded after engraving the value. The third point is the choice of materials. Nowadays, there are plastic, metal, and wooden rulers. Plastic rulers are mainly stationery used by ordinary students, ...
