Overview

The Platinum BISO Nebula Black catches the light in pearlescent resin, bringing shifting color to a slim fountain pen with contrasting metal details.

The pearlescent resin changes subtly with the light and the angle of the pen. Metal at the cap top, barrel end, rings and clip sets off the finish. BISO takes its name from the Japanese words for beauty and harmony, expressing Platinum’s idea of personal expression through writing.

Made in Japan, this fountain pen has a gold-plated stainless steel nib and accepts ink cartridges or a converter for bottled ink. Its overall length is 138 mm, with a maximum diameter of 12.7 mm and a weight of 18.4 g.
