Called the "uroko-mon" or scale pattern, this design forms a series of triangular shapes both in the positive spaces of the figures and the black negative spaces of the ground. It utilizes abalone to give the pen a reflective sparkle of a rainbow of colors, as well as gold and silver dust over a black Urushi base. The gold dust can be seen both in coarse form, making a rougher surface, and in finely pulverized gold dust giving a flat sheen. The silver has a grey tone which contrasts more subtly with the black base resin of this pen. Measuring 5 1/2 inches capped and weighing 21.2 grams, this cartridge-converter pen is also a wonderful everyday writing instrument.
