Hand-turned on one of my wood lathes, the barrels of this pen are composed of yellow acrylic with a strong black swirl.
The Diplomat model is one of my most popular pen styles. I elected a long time ago to use only the finest materials for the writing instruments I create. So, the metal parts on this pen are plated with glossy black chrome for a dramatic look and the mechanical parts are the most durable and dependable I can find. No finish is needed on acrylic pens; they are polished to a high gloss while still spinning on the lathe.
