This is a set of Pilot replacement leads, B hardness, 0.5mm. It is a case of 10 boxes, with 40 leads per box. They were stored together in a larger box in a dark place. The outer box is dirty, but the inner boxes have only minor scratches as shown in the photos, with no discoloration. Please understand that these are long-term storage items before purchasing. [I opened a different box to test and there were no problems at all.] I am not considering selling them individually. Immediate purchase and silent purchase are okay. Thank you.
