Pentel Super Hi-Polymer Lead Refills, Medium Point, 0.7 mm, 2H Hardness, Tub Of 12 Refills

These mechanical pencil refills boast a 2H hardness to produce crisp lines of consistent darkness, smoothness and density. 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. 0.7 mm medium-point lead with a 2H hardness produces strong, dark, smooth lines. Compatible with select Pentel pencils, so you can keep writing.
