The Gradient Markings On This Ruler Are Visible On Light or Dark Paper

Here's a simple but rather clever design improvement for clear plastic rulers that most of us would have probably welcomed back in grade school. Nendo's new Contrast Ruler features metric markings that fade from black to white, so no matter what color of surface you're working on and shows through, you can always easily discern the tick marks.

It's just too bad they're not available until April, roughly 10 to 20 years too late for most of us to really embrace this wonderful innovation. [Nendo]
