Carbon fiber embodies strength, durability, reliability and it is just plain cool. To be 5x stronger than steel yet lighter than aluminum is so amazing. Do you know someone who is extraordinary and who demonstrates strength, durability, and reliability? If so, our Carbon Fiber pen is a perfect gift that will be treasured for a lifetime. The design of this pen is a rounded-top black carbon fiber and the gold and gunmetal pen kit is a picture-perfect complement to the carbon fiber on the pen's body. On its own, carbon fiber is quite brittle and prone to splitting and cracking. To preserve its abilities, it's suspended in a glue-like material called epoxy resin before it's molded, forming a composite material that is exceptionally strong and durable and will last a very long time. Attributes: 5.25? length, .75? width, .63? height, 1.8 oz weight For a full description of what carbon fiber is and how it gets its incredible strength, see the video posted on our collections page (https://youtu.be/1JpfOjKrw58) Turn the bottom counterclockwise when replacing the Parker-Style refill (see photo for details). There is a spring inside the pen that you do not want to lose.
