I use these rulers in my classroom for graphing, and my students love them because they can see through the rulers when drawing a line on their graphs. The rulers don’t break easily (they are durable), and are easy to read with marks in centimeters, millimeters, and inches. I have bought these rulers twice now for my math and science classes.

Was exactly what I was looking for. First order arrived without the product in the bag. There was a hole on the side. Amazon replaced my order the same day and was to the house in two days.

Perfect clear rulers, with both metric and inches. Enough of a bevel that ink doesn't bleed.

I have bought 2 sets of these for my classroom for when I teach 1 and 2-point perspective drawing. They are sturdy, don't break, a good thickness and the kids can see through them in order to draw their orthogonal lines correctly. Definitely recommend. :)

Although these are nice, clearly labelled rulers. Easy to measure. Most of my students had them completely bent by the 2nd month. Several have broken, so if you are using these in a classroom, be prepared to replace them before the end of the year.

They are good sturdy rulers.The only thing that I do not like about them is that the measurements wear off after a short amount of time with use.
