Pentel Super Hi-Polymer Leads

Super Hi-Polymer Leads produce crisp lines of consistent darkness, smoothness and density in 0.5mm mechanical pencils. 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. HB lead is equivalent to a No. 2 pencil in darkness and guaranteed to scan on standardized tests.
