PILOT neox GRAPHITE set, including 0.5B and 0.5HB lead refills. - Brand: PILOT - Model: neox GRAPHITE - Lead diameter: 0.5B - Lead diameter: 0.5HB - Colors: Pink, Blue Thank you for viewing. This is a set of four lead refills for mechanical pencils that I used previously. It's a set of 4, with 2 of each B and HB (+ bonus lead refills). One of each B and HB has been opened, but since I was storing the same type of lead refills together, both of the opened cases have about 70 leads in them. Please be aware of this. As a bonus, I'll include mix color lead refills (0.5) and red color lead refills (0.7). Since these were stored by a non-professional, the opened ones show many scratches, etc. Please refrain from purchasing if you are sensitive to such things.
