Super Hi-Polymer Lead, 0.7 mm medium, HB, black lead, 30 per tube, 3 PK

Super Hi-Polymer Lead Refills produce crisp lines of consistent darkness, smoothness and density in 0.7mm mechanical pencils. HB hardness is equivalent to a No. 2 pencil and is guaranteed to scan on standardized tests. Lead is excellent for all general writing, including items to be faxed, photocopied and electronically scanned. Each super-strong lead writes as far as an entire wooden pencil and produces a dark line. A 30-piece tube is equivalent to 30 wooden pencils.
