The design of the product come from the selected 3 things: shape, material, and pattern

​

The shape comes from the perspective of the natural landscape. The beauty of the landscape from my perspective. The composition of them is composed of the various mountain ranges standing beside each other which become the giant wall with sky and clouds above. From those, I design the pattern on the ruler surface inspired by the outline of the mountain ranges. Which stand beside each other and the space represents the sky.
