On parts & builds
- “It happened to most of us: Our favourite ball point pen is suddenly out of ink. We search for another ball point pen to swap the refill. Only to discover: the refills are different. The new one does not fit. Well if the O.pen is your favourite pen this won’t happen again.” The pen fits to all available refills:
- ↑ This pen can hold different kinds of refills. The inner tube has an insert thread to lock the refill in place with a set screw.
- The images show different prototypes testing the same idea. It works. ↑
- Need a cap? A short piece of silicone tube will do. (See image with the black caps)
