Duragraph in Black Hard Rubber - This was the predecessor of the Endura and is essentially identical to the Senior Endura. This is the long model with an extended section and cap. These pens are hard rubber so they have all of the problems inherent with the material. Weak imprints are a significant problem with them. The wide cap band does a good job protecting them from cracks. Duragraphs were also available in Red Hard Rubber.
