Each Sailor King of Pens Grey Mosaic Rhodium Trim Fountain Pen is handcrafted in Japan, and production times can vary from six months to a year or more. The dark finish is reminiscent of a more opaque stained glass, made from an assemblage of resin. Without cap rings, the Mosaic Grey maintains a streamlined look.

Rhodium trim on the clip and plating on the nib lends a sleek style. This writing instrument can be filled with bottled fountain pen ink using the provided converter, and can also use convenient Sailor brand ink cartridges.

Sailor's smooth-writing 21k nibs offers a writing experience unique to this brand. The King of Pen size nib has a slight springiness which provides a different feel while writing.
The Sailor King of Pens Grey Mosaic Rhodium Trim Fountain Pen ships in a dark wood presentation box which includes all papers, a converter, starter ink cartridges, a polishing cloth, and a bottle of Sailor ink.
