This Cyclone Fountain pen is engineered and manufactured to the same exacting standards as the Executive series of pens. The pen is supplied with a standard size 6 nib (medium), cartridge and ink converter so you can use pre-filled cartridges or use your own bottled ink. The cap and barrel are crafted with an Italian-made, "Mother of Pearl" acrylic and has a deep, rich cherry red colour. The cap is non-postable. If you would like this pen created with different material, please contact JWI to find out how.
