This Atrax fountain pen features a gold finish and a unique acrylic called Middle Earth on the cap and barrel. Looking at it, you can see the deep, rich and shifting colours in the material. The steel nib is a #5 medium nib and writes smoothly and effortlessly. The cap is non-postable and the nib feed accepts an international fit converter (included) or pre-filled short or long cartridges. If you would like this pen made with a different material, please contact me so I can create the exact pen you are looking for.
