The strange blue color on the Cool Blue pen body is not always as clear as in the picture. Only in a moderate light, combined with the surrounding environmental factors, can you admire the full beauty of light and dark of this pen.
Sometimes when you leave this pen in a room with little light, it will turn into a dark blue color, the lines will not sparkle, but in return you will have a much cooler Starwalker! Basically, the Starwalker Cool Blue is designed like that, designed with blue lines that sometimes appear and sometimes disappear, like a playful game with light.
