3 Pack 12 Inch Architectural and Engineering Scale Ruler Set, Laser-Etched Aluminum Triangular Drafting Tool Imperial and Metric Conversion Standard Metal Ruler for Architect Civil Engineer Blueprints

these are so helpful

As described.

Good product that does the job.

I use these for school (I am in Civil Engineering) and they are great because they fit inside my pencil case.

Purchased these due to having a small desk. Worked perfectly well!

It's exactly as described, the color is amazing and it's fairly scratch resistant, but it's confusing as to what unit is what on the measurements standpoint, but it's accurate when you can figure out what unit is what.

I liked the size

This is a tiny and lightweight aluminum ruler anodized in red. It's handsome, well made, and will certainly be durable. My only problem is that this was supposed to be a two-pack and only the one ruler arrived. That is the reason for three stars. Otherwise, it's a five star.
