Grekywin 3 Pcs 16 inches Stainless Steel Straight Ruler, Extra Long Ruler, Double Scale, Office Drawing Measuring

These are great rulers. They are not too thin so they don't bend easily. The measurement markings are in very clear black ink and are stamped into the steel so they won't wear off. Also the markings are printed on both sides of the ruler. Very good price - only drawback is they are a little sharp on the edges, but I have never found a steel ruler that wasn't.

Very sturdy thought they would be a little flimsy but not at all
