Pentel Hi-Polymer mechanical pencil lead, 0.5mm HB, 12 pieces. - Lead thickness: 0.5mm - Hardness: HB - Quantity: 12 pieces - Brand: Pentel Likely unused. I've confirmed that the leads are inside, but I haven't counted them individually. This is a complete set, including the original plastic case to hold all 12 leads. The case has a dragon mark, making it a rare item. The case has multiple scratches. Please understand that this is an old item before purchasing.
