Shrouded in Black Titanium and Rhodium, the barrel and cap on this hand made pen were crafted with a colourful "Lava Riot Explosion" acrylic. The cap is non-postable but the pen is well balanced and fits the hand well. The nib is a #5, German made, iridium tipped steel nib designed for smooth writing and longevity. The pen comes with an international fit converter so you can use your own bottle ink or if you choose, use long or short prefilled cartridges.
