The Sonic Nobirura Extendable...
, October 29, 2013
The Sonic Nobirura Extendable Ruler is a must for any math, science or OCD
student out there! With its retractable feature, this ruler can be easily stored
in a regular pencil bag, then extended for its full potential when needed. At
first, I was skeptical of the section that slides out. I thought maybe it would
break off easily, come loose or get stuck. To my great and happy surprise, the
extendable section slides out of position smoothly and clicks into place to line
up for the full 30 centimeters. With the clear body, it is easy to line up with
ruler with anything and will surely fulfill any OCD tendencies.
I do caution you that sometimes the second half (extendable half) will bend side
to side under pressure, so your lines may sometimes be crooked. To make sure it
does not move, hold down both sides of the ruler with one hand--your thumb on
the extended portion, your middle three fingers on the clear section, and your
pinky and palm on the table or solid surface.
