OEM Pentel Super Hi-Polymer Lead Refill, featuring 60 pieces per pack. This lead produces crisp lines of consistent darkness, smoothness, and density in 0.9mm automatic pencils. HB hardness is equivalent to a No. 2 pencil, making it ideal for general writing, including items that need to be faxed, photocopied, or electronically scanned. Each piece of lead writes as far as an entire wooden pencil, providing excellent value for young writers and first-time users of automatic pencils.
