12" triangular scales are ideal for engineers and engineering students. Three sides with six different scales feature die-engraved graduations. Easy-to-read, printed graduations will not rub off. Engineer triangular scales are fully divided: 10, 20, 30, 40, 50, 60 parts to the inch. Scales are made of high-impact polystyrene plastic.

I bought ten of these for a middle school math club. The quality is good for the price. As opposed to something I read in one of the answered questions, the scales are indeed engraved, or rather cast into the plastic, so they should wear very well. One of the darling students went after one with a sharp metal straightedge and ruined the edge of one of the scales. That's just plain vandalism, but indicates that the plastic is not super hard. Very good for showing the concept and advantages of scales made in engineering units rather than architects'.

This scale is as durable as the one I had in college. I use it every day to mark up drawings.

We use this for Nursery/Landscape problem solving within a contest. I’ve purchased 5 of these and they work great!! Numbers are easy to read!

Staedtler makes the highest quality rulers. I enjoy the ease of readability and accuracy. It doesn’t feel like cheap plastic and is sturdy.

Llegaron un poco chuecos. Si los pones en una superficie plana se pandea o se hace un arco.

Bonne qualité, mais il n’a pas tous les échelles. Je cherchais surtout pour l’échelle 1’=1 1/2‘’ donc ce n’est pas une échelle d’architecture.

I've been using these for Staedtler scales for 30 years and have never come across on that didn't have a colored strip to distinguish the sides. Very inconvenient, why would they change that??
