This "kitless" fountain pen features a deep and lustrous green and black acrylic, polished to a high sheen, bringing out the most from this material. Each of the threads has been carefully hand-turned, with a triple start thread on the cap for easy on-off operation. The #6 medium nib is a two-toned, German-made, iridium tipped for a life time of smooth writing. The pen comes complete with an international fit converter so you can use your own bottled ink, or if you prefer, pre-filled cartridges.
