Hand-turned on one of my wood lathes, the barrels of this pen are black acrylic with a purple swirl. This pen features a capacitive stylus on the end for use with any device with touch screen sensitivity.
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 nearly all my pens are plated with expensive platinum and black titanium 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.
