The intricate pattern on the body depicting a layer of thin clouds is created through a detailed facet cutting. It produces depth and refraction of light that reproduce the image of the beams of light extending from clouds, as if they were shining down from heaven onto the earth. Also, a part that resembles Mount Fuji is placed at the top of the pen, expressing the mountain enveloped in purple colors.
Each new pen is marketed worldwide in a limited number of 3,776, which is the height in meters of Mt. Fuji. Each pen comes with an engraved serial number.
