The Pentel Orenz Mechanical pencils offer the convenience to write or sketch nonstop. The unique super sliding sleeve protects lead and prevents it from breaking even using very fine 0. 2mm and 0. 3mm lead – plus it automatically feeds lead out as you write. Simply click once to advance lead and keep writing. Each pencil is pre-loaded with Pentel super Hi-Polymer “B” lead, which never needs sharpening. Hb lead refills (same as a #2 Pencil) are available separately. Available in 0. 2mm, 0. 3mm, 0. 5mm and 0. 7mm lead sizes.
