Unless you are student, or a person who does technical stuff or draws, you probably hadn’t look at a ruler for the longest time. If you are one of the aforementioned, or someone who just need a cool ruler, then you may want to take a look at 30° Ruler 4.0 by Orangered Life.
30° Ruler 4.0, as the name explicitly implies, features a 30° slope that makes it easy to pick up without sliding it to the edge of the desk. Having an angled ruler also allows you to read measurements without leaning over and also makes it safer to be use as a cutting guide.
It also helps that every tick mark is labelled, so counting lines to determine the exact measure is a thing of the past.
It further features dual units of measurements (namely, centimeters and inches), start from zero at the edge of the roller, non-slip design, and laser engraved markings that is totally scratch proof. It also promised accurate measurement, but I am not scientist, so I can’t say how that can be assured.
