A set of 12 MITSUBISHI uni pencils with eraser. The lead hardness is F. Hardness F is between H and HB. This is a new, unused item, but it is quite old, so there is some deterioration over time. There are some scratches on the lid of the clear plastic case (see photo 10). The eraser is included, but it is unknown if it can be used (due to aging). Please purchase with your understanding and acceptance. Thank you for looking.
