Uni's Nano Dia mechanical pencil lead provides a smooth and consistent mark. Unlike conventional pencil leads, the Nano Dia series have nanodiamonds embedded between the graphite particles, allowing for less friction to occur in the structure of the lead itself. This translates to a better feel and quality in each mark made. Now available with colors, the Nano Dia Color leads are easily erasable without being too brittle to write with. These features make it the perfect aid in studying or marking up notes.
