Click only once to extend the unique Super Sliding Sleeve and keep writing until the sleeve fully retracts then click only once again. Lead should not extend past the metal tip - it will write without you actually seeing the lead. Unique Super Sliding Sleeve prevents lead from breaking. Pre-loaded with Pentel Super Hi-Polymer "B" lead; never needs sharpening and produces a clear dark line. Retractable tip to protect pockets and purses. 0.7mm. Sky Blue Barrel.
