needs more advanced ink description to be practical
This charcoal pen is useful in developing countries as some school supplies cannot be found and afforded in low class towns and villages. This pen was designed as a benchmark design for solving that problem! This project is in response of the OSAT project, projects that are meant to change the world for the better. It is still in development and should be tested more as well as possibly edited in its design if need be.

Take any charcoal or coal that you have available and crush it into a semi chunky powder/paste. Make sure that it retains its color so that it will show up on paper. Next take the charcoal and insert it into the end of the pen. Once this is completed, take the Bolt and begin threading it into the pen. Once the charcoal/ powder leaves the vessel, it is ready to use.
