Click just once to extend the unique Super Sliding Sleeve and continue writing until the tip retracts completely. The graphite should not protrude beyond the metal tip; will write without you actually seeing the graphite. The unique Super Sliding Sleeve prevents the graphite from breaking, even with very fine graphite. Pre-filled with Pentel Super Hi-Polymer graphite leads "B"; never needs sharpening, is super durable and produces a sharp, dark line. Retractable tip to protect pockets and purses.
