I was fascinated by the soft black color and texture of ebonite, and I wanted to make an ebonite ballpoint pen. Combining my limited knowledge in the initial proposal, I could only think of a cross type for the central rotating mechanism. Three years of taking notes and laying them down... As I remembered, I picked up the feeding mechanism I had at hand and created it.
The refill has changed from a cross type to a parka type. Fits Jetstream parker refills. A ballpoint pen with no fixed name.
