Detachable Magnetic Ruler / Ruler

Detachable Magnetic Ruler
Detachable Magnetic Ruler

The ordinary ruler which has the part without scale at the initating terminal is not suitable for measuring the height of small objects at the horizontal plane.
The Detachable Magnetic Ruler can be separated into three parts, including two ends and one independent ruler, which are built in magnetic sticks. Moreover, the scale of the independent ruler starts directly from zero without blank space. Through this structure, the zero scale line can be stuck on the plane so that the height of an object that is placed at the horizontal plane can be measured.
