Every start of school year, one of the items on the list of stationary supplies is a 30cm ruler. It is used for measuring the length and width of objects, drawing straight lines, cutting straight lines, marking page margins, and in understanding and solving math problems. The advantage of flexible plastic rulers is its flexibility for measuring uneven or curved surfaces.
