Orenz mechanical pencils feature a unique anti-breaking lead system - click once to extend lead and keep writing until Super Sliding Sleeve retracts fully into barrel. Click only once to extend the unique Super Sliding Sleeve and keep writing until the sleeve fully retracts. 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- even very fine 0.2mm and 0.3mm lead. Pre-loaded with Pentel® Super Hi-Polymer® "B" lead; never needs sharpening, is super strong and produces a clear dark line. HB lead refills (same as #2 pencil) are available separately. Retractable tip to protect pockets and purses.
