This fountain pen has a warm gun metal finish surrounding a "cappuccino swirl" coloured acrylic. The cap is postable onto the barrel so the writer can change the weight of the pen when writing. 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. Care for a different material?
