Professional Grade Scale Ruler
I'm very pleased with this scale ruler. It is way better than the plastic screen-printed rulers that I have used in the past where the markings would eventually rub off. This ruler is made from solid aluminum and features die-engraved markings that are easy to read and should last forever. I would highly recommend this professional quality product to anyone.

Easy to read scale
Needed this for a class, easy to read, easy to flip/use. Solid material and does not scratch or stain. Came super fast when ordered, and I'd order Allen scales from the same company if they have them...
