Easy to make, elegant and practical these Slimline Rhodium pen kits are 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. Includes an attractive I.D. card which identifies and explains the rhodium plating. It also includes a space for you to sign the project and give information about the turned wood you used.
