The days of exerting effort to align your specimen in question with the edge of a ruler are over with this concept called the 0 Point Ruler. In its passive state, the hi-tech office supply has no numerals or notches on it whatsoever, only producing them when the tip of your pen touches the pressure-sensitive material.
This technology is especially helpful if you're using the implement to draw lines of particular lengths. Simply place your pencil next to the measuring stick and the zero mark will appear. So that you can choose which direction to draw, the numbers rise in increments of one on either side of the nil value.
To maintain the innovative 0 Point Ruler, spin it around on your finger regularly and the kinetic energy will power the device.
