The raden rectangles, stacked one on top of the other, mirror, top and bottom, the way calm water reflects what is above. Adding to this effect, the refractions from the raden intensifies the effect, changing color as the pen is rotated. With raden technique, the inside surface stratum of various shells such as turban, trumpet and ear shaped shells etc. are peeled off in a thin layer. They are then cut into small pieces and these are coated with Urushi lacquer to secure them in place. This is then burnished to create a finish. This fountain pen comes with a retractable rhodium-plated 18k gold nib - just click to expose or retract the nib. A hidden trap door helps keep the nib from drying out when not in use.
