Super Hi-Polymer lead refills, 0.9 mm, HB, 15 per tube, 15 EA/TB

Super Hi-Polymer Lead Refills produce crisp lines of consistent darkness, smoothness and density in mechanical pencils in 0.9mm 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 12-piece tube is equivalent to 12 wooden pencils.
