The Konrad flex fountain pen was introduced in 2012, and updated with this Konrad Cardinal Darkness model in late 2015. It is shorter and thinner than the Ahab, but is larger than the Standard Flex Nib Creaper. It features a flexible #6 steel nib and ebonite feed, and fills via an internal twist piston mechanism, which is hidden under a blind cap. Creator Nathan Tardiff is proud of the fact that this pen is made of celluloid derivative and is technically biodegradable and formed from a "renewable resource".
