In the Japanese culture, the owl, or "Fukuro", means luck and protection from hardship or suffering. Using ebonite as its base, the Rankaku Maki-e is used to design both the owls on the pen, and the Raden technique is used to embed the eyes of the owls making them sparkle. A layer of clear urushi lacquer is then used to protect the surface of the pen giving it a glossy polish. The Rankaku artwork is simply outstanding with the incredible attention to detail.
