Rulers with clear scale / Stationery

Rulers with clear scale
Rulers with clear scale

When we measure black or dark objects, due to the fact that the scale of ruler is black and its brightness is similar to those of objects, it becomes rather difficult to identify the scale quickly and accurately.

Now, we change the color of scale into gradient color from black to white. Thus, no matter how bright the color of objects we want to measure, clear scale can always be identified accurately and immediately.
