A ruler should be firm, straight, lightweight, and small in size. It should allow you to create straight lines and also assist you in sketching. Whether you use one for office work or school work it should stay with you for a long time. As you cannot go to the market every now and then to purchase a new ruler. This is why you should buy an ORO 6-inch plastic ruler. It is a strong ruler with smooth edges and it has a long lifetime.
So if you need a new ruler, don’t think, just buy ORO 6-inch plastic ruler.
