This Rollerball pen is plated with rhodium, an exquisite and valuable precious metal from the Rhodium chemical group. Rhodium's brilliance, hardness, and beauty make it a favorite of fine pen makers and collectors. Rhodium is extremely durable; it resists tarnish and is very resistant to scratching, and acids. The wood is highly figured and shimmers in the light. Includes premium German made Hauser rollerball insert.
