A 30cm plastic ruler is a measuring tool made of plastic, with a length of 30 centimeters. It is commonly used for drawing straight lines and measuring distances in school, office, or home settings.
The ruler is lightweight, durable, and often features markings in both metric units (centimeters and millimeters) for precise measurements. Its plastic material makes it flexible and less likely to cause injury compared to metal rulers.
Ideal for students, artists, and professionals who need accurate measurements in their work.
