Yippee, it’s imperial
Have always hated metric measurements, so to get this makes me feel comfortable in knowing what I’m doing. Clear figures and nice sturdy construction and weight.

Light but sturdy
I needed this for cutting card with a craft blade and its triangular shape protects fingers. The measures are all metric so make sure you don’t need imperial. A good tool.

Very Practical Tool
A useful tool for my drawing. The shape helps me to move it around easily. The markings on it are very clear and the ruler feels substantial and good quality. I am also pleased to have found a ruler with exclusively inch measurements and not metric. It also comes in a rather nice plastic box like a Toblerone box! Pleased with my purchase.
