Magic Graduation / Ruler

Magic Graduation

General ruler, which made of transparent
plastic, printed the black numbers and
graduations on the surface, due to its better
usability of ruler, is the most accepted and
used one. However, when we use it on the
black or dark color paper, it is hard to read
the information on it .

The new design only adds a white frame
on each black numbers and graduations.
When we move the ruler on the dark color
paper, the frame will magically appear,
and then we can read the information
clearly. Just a bit of manufacturing costs,
but the usability has improved a lot.
