Perfect for engineering, very durable and accurate. Use is easy specially on edges. The tickmarks vary by measurement and are easy to read. Looks very sturdy and can be beaten on a little bit before showing signs of wear. I’ve had this for class and use it everyday.

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

This STAEDTLER engineering scale ruler is made of great material and very precise. After using it for a while, it still works perfectly. Excellent tool!

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.
